Assembling this Germa toy is on my German father's to-do list.
He reads the instructions while cringing at the news. (Much less cringing, of late.) I will report again once he starts playing with his toy.
Thank you,

I gave it to my son in law who has always loved puzzles. He loved it. I have not seen it because of Covid and visiting. I just wanted you to know he loved it! I was going to order another for his birthday. Thank you!
Erika M.
Still working on it but love that it makes me think to get it right!
Cynthia L W.
This gave my son something to do while everyone is social distancing. He enjoyed it very much and it actually works.
Audrey M.
My son-in-law put this together. It was his Christmas gift. He sent me a picture of it working as he cranked the handle.

It was fun to build, I added a few braces, Motorized it with a speed control and added led lights. I also put in a wire clip I made out of a yellow paper clip. It only allows one ball at a time on the ladder. I sent you a short video but I guess you did not get it took a few minutes to load. The photo shows the motor, speed control and Led box. The battery box is on the back side. 4 AA with an off and on switch. When the ladder goes up a ball rolls in and the clip drops down between the next ball allowing only one ball to enter. It takes a few bends to get it to work but once you get it right on it never misses. I am in the process of making a Super Hero Card house for my great grandson. I will build another project when I get this one done.

This is my first model like this and it went quite well. I was quite happy with the quality of the parts and how they were cut. The assembly instructions were clear and complete with one exception. On page 16, step 22, it does not give any guidance on which way sub-assembly k should be mounted to sub-assembly j. I didn't realize that it mattered so the unit would not lift marbles up to the upper rail. When I reversed it such that the large holes were away from the crank side, it worked fine.
Otherwise my experience was quite enjoyable.

Nice product, fun to put together, works great.
Ken M.
It took me a bit of time once Christmas was over to start finding time for the construction of my Marble Run but once I got some steam going and a couple of kinks worked out, it was up and running and amazing! Now, I'm wondering about my next ROKR project.
Barry D.
Wow it blew me away when I opened the box. So well made, excellent quality. Instructions are easy to follow. The completed locomotive will look amazing. Wouldn't hesitate to buy another set.
Diane L.
My husband loved doing this project it was fun and it really works.
Bev P.
It was challenging and enjoyable. The top of the ladder needed modification in order to have the marble drop (I notched the top of the wall or the marble would not drop). I broke one of the track supports because of the odd angle to install and supported it with glue and toothpicks. The track works well with the modifications and fixes. I am looking forward to my next one.

This is a very sturdy marble maze. I purchase 4 of these. One for each of my children and their families. I assembled the 4th one in about 5 or 6 hours and really had a great time doing it. I highly recommend this for anyone who enjoys putting things together as these are very well made.
Michaelann J.
I ordered this for my son for his birthday. I just gave it to him yesterday and he loves it. He hasn't put it together yet but I will update review with pictures when he finishes it. Excellent updates on shipping and arrival time.
Bob M.
lots of fun worked on it a few days
instructions were easy to follow and it works
great winter pandemic project
Josée S.
A very good quality product. Not too complicated but the mechanism works well and building it is a lot of fun. Great quality price ratio. Would buy other products.
Sally A.
I am a sixty two year old kid and I loved it! as much fun to make as it to play with!
David C.
Easy instructions. Very enjoyable several hours of assembling.
Linda M.
Found this excellent
Have had problems with temper sometimes
This was challenging but helped in controlling said temper
Looking to do several more
Excellent
Barbara H.
I bought four different sets for hubby as Christmas presents. He absolutely loves them!
John M.
This was my first time working with one of these wood kits. It has been a great experience and a good way to relax in this pandemic time. The instructions were clear and easy to follow. The pieces separate easily and fit together well. I am almost finished my first Roller Coaster kit and intend to order more. As a 67 year old I find it's a great way to stimulate the brain and promote manual dexterity. Thanks for a great experience!
Penny H.
Mail took a lot longer than expected around Christmas but arrived in perfect condition. My 10 year old grandson is putting together. So far, so good.
Lindsay B.
Fun to build. Great boredom buster.
Eileen S.
My son loved it! It took him about 4 hours to put together and we have both played with it. I love it. I'll be ordering more for him.
Kathy’s C.
Just started to assemble it
Kerri S.
Some areaS could use more support beams
None the less device is working well
Carole T.
My husband is so hard to shop for, and this kit was unique and I’m so happy I ordered it. He really enjoyed putting it together. The quality is excellent as well.
Fay M.
I really enjoyed building this model and figuring out a few different challenges. Overall, the model worked great, except for one issue with the elevator. The elevator reached to the to with the bearing, but I had to tip the platform slightly to push the bearing onto the slide. I had to add 1mm to 2 mm to the lifter in order to allow the bearing to offload on its own.
Still a fun toy!!
Thank you.
Jean Magne
Blanche M.
So far so good. Haven't put it all together yet but what I have put together looks great. Enjoying it.
Andrew S.
Great to put together and son loves to play with it.
Joan B.
Project fits well together and the directions were clear. The marbles transitioned well with optimum interest.
Susan C.
Enjoyed the journey. Very cool!
Curt F.
We bought this for my dad to build with our niece and nephew over Christmas. They had a blast building this together, and the outcome was truly amazing. Ingenious design. Would definitely recommend.
Genevieve G.
Looks great. Works great. Super fun to assemble
Éric M.
Fun to assemble, very well designed and constructed. The kid loves it!
Kristin R.
My husband absolutely loved this!! I call it, "legos for adults"....thank you!
Nadean Y.
My almost 3 year old grandson is mesmerized by turning the wheel and watching the balls roll through the run.
Mary W.
amazing craftsmanship. So impressed, I bought one for my father-in-law in hope it will keep him busy during these times.
Ritsuko B.
Interesting product for family!
Carmen A.
Pretty cool!
My boyfriend loves it!
Jeffrey S.
Great activity putting this device together and super fun operating it for family and friends.
Peter H.
First time to build a laser cut wooden model. Impressive engineering! It would be interesting to know how many CAD hours and how many iterations were needed to achieve this design!
In spite of the great engineering, one problem with thin plywood remains the amount of warpage that can occur. A day after unwrapping the shrink-wrapped panels, the thickest showed more than a small amount of warp. Since this panel contained the main vertical support pieces I was worried that the result would be interference of the moving parts attached to them.
Yes that did happen, but I was able apply enough gentle force to get the assembled model to hold its shape so the mechanical parts would work smoothly. It continues to function very well for a week now.
It might be helpful to include instructions on how to flatten a warped panel before removing parts from it. I have read of some buyers wetting and pressing the panels flat while drying them. Since this is probably a common problem (at least in dry climates) a remedy should be offered as part of the instructions.
Peggy C.
Learning to be so so very careful and patient with the wood makes me a new person!! Working on placement of the moving parts takes more patience. But once completed and tweeked, it worked great!!
Jill E.
I got this for my very brilliant 5 year old grandson. He absolutely LOVES it!
Thank you!
Maria D.
This was a gift for my nephew who was so focused on putting together he didn't pick up an electronic device for over 6 hours! Awesome! He loved it.
Debra .
Fun and challenging, looking forward to doing another. Easy to follow instructions and diagrams.
Andrea S.
I bought this for my nephew for Christmas. I think he is going to love putting it together with his dad.
Heather C.
A fun way to spend a cold weekend inside with my teenage daughter. This is a natural next step from advanced Lego building.
Kathryn W.
We have not opened the box as it is a gift. We have had no feedback as of yet other than they think it is cool and they are working on it.
Susan k. D.
This is an extremely intricate thing to assemble. Not for any child and more for the mechanically inclined person. Some pieces are smaller than rice and require a steady hand and a focused mindset. My husband is mechanically inclined and found this to be a huge challenge. When completed it is really cool to wind and watch it function.
Dorothy W.
Fun project
This one had me hooked in about 10 seconds
Didn't stop assembly until I had it finished
Had to do a little sanding on several pieces to get them to fit and lock together but not much of an issue
Ronda K.
Hubby and son spent about 6hours putting the project together. They had a great time. (Just a note: my hubby has early dementia and this kept him well occupied.) The only thing I would say is,, it is a lot smaller than I thought it was, but the guys still had fun putting it together.
Frank D.
This was a great project! Directions were easy to follow, the parts were well marked and fit perfectly. A nice project to start, work for a while, stop and continue later.
Really enjoyed working on this and will buy another.
Michael B.
Bought as gift. Final product looked as advertised and no missing parts!
Chris Y.
My husband loved this as one of his Christmas presents. As an engineer, he loves to build things and he got right into building this!
Margaret C.
This was such a fun Christmas gift for my husband and son. They loved having something they could do together on Christmas day. Thanks!
Gene K.
Challenging but fun to put together.
Jim B.
Very impressed with engineering and manufacturing of this product, so much so I ordered my second one!
Jody M.
I built this with my 11 year old son. I realize he's a bit younger than suggested but it's good to challenge them and he really took to it. Learned a lot about gravity and how important it is to always measure twice and cut once, as it applies to this project. I will admit as the adult I was a little surprised that in a few places very subtle little differences in pieces that were very important were almost glossed over in the instructions. It caused us to have to disassemble and redo a couple of pieces, but a good teaching moment overall. At the end of the day it looks great and works well and he's quite proud of himself and is enjoying showing off our work to family and friends.
Chris V.
Great fun building and it works great.
Kirstine C.
Loved it. Especially well done. Very easy to understand and put together. A joy.
Pamela C.
Purchased for grandson for Christmas. He was very excited! Not sure if he has put it together yet or not.
Pamela W.
My son loved it. It works perfectly!
Rachel H.
Only work on the ball roller a couple hours at a time. It is definitely a challenge.
Elizabeth M.
I am enjoying my Marble run...I have made one or two mistakes...but when I went back and reread the instructions it was entirely my fault and easily corrected. The video also was extremely valuable to insure I was on the correct path. My only recommendation would be the ability to show the video in slow motion. I have just ordered a second model
Mary L.
My sever-year-old grandson and I started the Marble Run yesterday. What a great project for the two of us together! He is so excited, and I'm enjoying working with him. We made it to step 30 in two days, so with school starting tomorrow, it will take us several more evenings. The pieces fit perfectly and the directions are very easy to follow. He punches out the pieces and keeps them in perfect order while I fit them together. I will definitely do another one as my grand children get older.
Janet B.
My daughter just moved into an apartment with friends, and flipped when she opened her gift. She said she wanted to set it up on a table and have everyone help out. I can't wait to see the finished product. It made her Christmas.
Angela R.
Am just about to finish the last steps to complete my first piece. Am glad I treated myself to this fun 3-D puzzle of sorts, can't wait to get it completed!
Pamela P.
Having fun putting it together
nancy P.
Can’t wait to start.
Andy S.
Everything was delivered as advertised. Complete and top quality. Construction is easy enough but takes thought and you need to follow directions.
Tim H.
gave it as gift to my father. he loved it
Wayne H.
Have not started the assembly, but, directions are clear and to the point.
Rita B.
Such fun and so unique
Judith H.
Sent for Xmas to man who has everything and loves to build wood items. Usually working on practical items of furniture. Loves a puzzle and this one fit the profile!
Gina B.
These wooden projects are AMAZING!!! I bought all 4 for my son and he’s not stopped building since he opened the box up. He’s 15, so they’re not just for smaller kids, like some others. Just LOVE these!!
Kathleen O.
I can't review the product because it was a gift, but the family I gave it to was very pleased with it and looked forward to working together on the puzzle.
Janet O.
Gave this as a gift to my dad for Christmas! We've had such a wonderful time building this model together! Pieces are well made and directions are easy to follow.
Maria d.
My husband is working on it now and is very impressed with the craftsmanship and precision of the cuts. I can’t wait to see it finished!!!
Janet M.
This was a gift for my grandson. He couldn't wait to put it together, which he was able to do i a day. He just loves it
Dorothy M.
Seems to have worked fine, instructions were really good.
Roseann M.
It was so much fun to build! The whole family is looking forward to doing more!
Robin S.
These kits are fantastic!
Robin S.
Great quality with a challenge for young minds to learn from.
wei c.
The pieces are precisely cut. Great fun putting it together.
Kris H.
Enjoyed working with the wood. Looking forward to the next challenge!
Sarah P W.
Sometimes challenging to get the pegs to properly join pieces. Very satisfying to complete.
Jacqueline W.
My husband and sons had a wonderful time together doing this marble run. It was one of the highlights of our family time together at Christmas this year.
Terrilynn B.
My husband loves puzzles, I love rollercoasters, this was a great compromise. My husband was so impressed with the precision cutting of the pieces and that there were extra pieces for any accidents that may happen. He liked putting it together with the easy to follow directions. His birthday is coming up, I definitely want to get him another, I just have too many on a list to choose from.
Rebecca B.
Gift for my husband and he loved it! Wants a new one each year!
Ruth B.
This was the first wooden mechanical model I’ve ever assembled. It was fantastic! The instructions are clear and accurate, with videos to support the complicated bits. The pieces are clearly marked, and fit together perfectly. Best of all, the model works! Love it!
Mark P.
I would share a photo, but I haven't finished putting it together yet. I'm doing it little by little so that I can extend the enjoyment! The pieces are beautifully engineered, and the instruction booklet is clear and easy to follow. This is my first attempt at putting one of these models together, but it surely won't be my last.
Jon F.
I enjoyed the building it. The step by step instructions were precise. It was very rewarding experience. My wife and like to watch it work. It gives a calming effect.
Suzanne F.
My Husband loved both of his gifts.
Sheron Y.
I bought this kit for a Christmas gift and when it was opened he exclaimed I've always wanted to make one of these. I can't wait to see it when he finishes.
Chrisellen M.
My daughter and her boyfriend, both engineers, had a blast putting this together. It is really cool!
