Haven't seen this in action yet since it's a Christmas gift. My son is a Mechanical Engineer and would make "marble runs" with his Legos all the time as a child. I know he's going to love this! Can't wait to see it when completed!
Chris M.
Did not disappoint! I’m a fan of making balsa wood models but this takes it to a higher level. Extremely well produced and the instructions were bang on. Every part fit together perfectly and there was also some thinking involved, never boring. I look forward to the next purchase and have already recommended it to others.
Well done!
Chris

This really works. So much fun putting together.
Love it.
Wendy S.
She loved building it, it brought her closer to her dad who has passed and was quite the engineer
Donna T.
My three purchases were for Christmas gifts for my 15 ye old great grand who loves Legos. I thought she would appreciate these projects.
Nicola R.
Built it with my 9 year old granddaughter. Not sure who had more satisfaction and fun in the process.
Ray D.
Fun kept me busy while I was recuperating
Joshua H.
My Son and I had a great time assembling this puzzle!
Ann C.
Fantastic precision laser cutting. Alittle hard on arthritic thumbs, we grunted a bit but laughed a lot too….. we did it as a couples date night over a few nights in a row
Daniel F.
Great fun , loved working on this one. Works like the ad shows and sturdy.
Guy G.
Being 68 it brought back memories of building model cars. It was fun.
Tava F.

the orders were birthday gifts for a nephew and a granddaughter. We ordered two products for ourselves, one a future gift for my wife and one we assembled immediately. Enjoyed assembling the owl pencil holder and have had many favorable comments concerning the look of it. These are high quality products and we highly recommend their purchase. Jerry Ehmke

So far we are loving the design and instructions. We have chosen 1 day per week, wife & myself…we are in our 70’s to work together constructing this product. Instructions are very good and as architect we are having a lot of fun. We hope to get it done before July for our grandson’s birthday. I think it is achievable. I am so glad I found this product on an application on an iPhone (Solitaire). Looking forward to buying other that I saw on the website. Love it….
Paul G.
I found the model very precise and well engineered. The instruction booklet was extremely detailed and easy to follow. I was surprised at how strong the thin plywood material was. Very enjoyable build. Thanks for a good product.
Suzan F.
Absolutely AMAZING quality! My daughter loved it!
Tom C.
I am very impressed with the marble roller coaster. The parts were all precisely cut and the instructions were perfect. Everything went together per the instructions. I remembered to use the wax where indicated and everything functioned great. On the first few runs, a marble would occasionally fall off until I realized that one connection was not properly snapped in place. Once I fixed that, it runs perfectly. I was surprised because construction sets often don't have great instructions but that was not the case here. Thank you for the fun!
May B.
A lot f fun putting this together. Interesting to watch when finished.
Anthony P.
Not very hard to assemble as long as you follow the instruction manual and take your time . Once you get it done right it works flawless. Great conversation piece, every one can't help but give the crank a few turns.
Robert S.
I built this with my 33 year old Son-in-law. We had to do some final fine tuning and then it worked exactly like the picture shows.
Lynda M.
This is a birthday gift for my grandson! We’ll see how he likes it.
Heather K.
This is mine part way thru build. This is the 4th model I've built! Love them!

My husband "whooped" when he opened it!! So excited to build it...
Keith F.
This is an intriguing device - carefully designed and engineered so that when correctly assembled, the assembler can feel proud of the finished product. It works as intended and is an attractive show piece, sure to fascinate all who come to view - and perhaps play.
Victoria C.
Bought this as a Christmas present project for our 10 year old grandson and his dad. They took two days assembling it and had a ball working together. Plus, at the end, it actually worked! They were delighted with the contraption and so were the grandparents, us.
Denise C.
Purchased this for my son for Christmas and he loved it. Couldn’t wait to put it together. It’s truly amazing how well it’s designed and we will definitely purchase more!

Gave it to my 7 year old grandson for Christmas and he and I put it together. We had a good time and it fit together really well and worked great when we finished it.
Linder J.
My husband loved it as one of his Christmas gifts.
Ken B.
It's been a pleasure putting it together and the quality was excellent.
Melessia T.
Absolutely loved building this. Everyone that sees it wants to play with it and then can’t stop. I’m excited to buy another one.
Stephen K.
Very happy with the quality and workmanship that went into this marble run. It’s amazing to see how accurate and intricate the pieces are and yet robust enough to assemble. I would recommend a kit to anyone who likes model building or marble runs. I have 2 so far, more to come.
Kristy R.
I enjoyed building it and the family enjoyed watching it being built! Well worth the money. Would order again.
Wanetta H.
Great family project! We enjoyed the challenge and the time together as a family!
Mia L.
Very cool coaster. My 10 year old was enthralled with building this and it took him a couple days to get everything together. Beefy design, and cool concept that teaches about building and mechanics. Highly recommended!
Adrienne P.
This is very well crafted. My adults sons thought it was a great puzzle to work for Christmas. Reminiscent of a toy they used to love. Will definitely buy another model for future fun!
Michael K.
Gave as gift, so have not seen or experienced the product. However, service and communication was outstanding.
Audrey S.
Bought this as a gift for my husband. It is nicely designed and was fun to put together. Everything works well together, the marbles run very smoothly and is calming to watch run!
Robert L.
I bought this as a gift for my crafty 16yr old daughter and she loved it! Took some patience and a pair of strong hands to finish. Only took us two days. Now she wants something bigger and harder LOL
Kieu N.
My son worked on it and finished it within a few hours and he love it!
John C.
Bought it for my grandson. It was truly unique, he loves it at 13 years old
Nancy S.
My grandson loves this Marble Run. He is putting it together and he finds it hard to pull himself away from it. He is enthralled with all the moving parts and loves the interaction. He enjoys being challenged immensely. This is a great product and a great teaching tool for children with higher IQs.
Louis H.
This is SO much better than I expected. The instructions are clear, the pieces fit with perfect tolerances, wax and wrenches are a delight. THIS HAS BEEN FUN!!! Who knew? And we have competition, now with assembly! My 93 year old Father has stayed up past his usual bedtime to add "just one more piece". I can't even begin to think what we will all do if it actually works. Magic!!
Debra W.
Got it for my husband for CHRISTMAS. He hasn't put it together yet but it arrived on time and I excellent shape...
Jeanne W.
My daughter and I made this marble run. She loves it and I like that there is no glueing or any tools needed. Very sturdy construction. Can't wait to make the others we got her for Christmas.
Kevin M.
Quality is great and had a great time putting it together. Can't wait for the next one!!!
David H.
this was a Christmas gift for our entire family-after all the presents.the visiting.and the dinner-we all gathered round to build our puzzle.one cooperative evening under one roof. After lots of Egg nog. hot chocolate and several stories later we had a working marble run that fascinated everyone-simply the best holiday we could have hoped for
Thank you!!!!
Lisa E.
I purchased this as a gift for my grandson. I spent the time to make it for him prior to Christmas. It was a wonderful project and I was so impressed with how this company designed/engineered this! It was awesome! I will say it is somewhat delicate because it is made of almost entirely wood pieces and even the pieces that are like pins that hold it all together are wood. mMy grandson absolutely loved watching the steel marbles travel in the two different tracks. It was a very successful gift!
Patricia H.
I bought it for my son for Christmas and he loves it. He’s looking forward to putting it together.
Roland H.
4 gifts to the 4 guys in my family and they all love it!
William N.
I enjoyed it very much and it was a great way to relax. Looking forward to the next one.
William N.
I enjoyed it very
Rick C.
If you liked putting together car models when you were a kid, you're gonna LOVE this! Plenty of intricacies to keep you busy here, so be sure to follow the assembly instructions carefully when you build it. Everything's friction-fitted for easy assembly without glue for the most part - only one place on one of the raceways where I needed to use a drop - and when you're done building it, and drop in the marbles and crank away, that's when the next part of the fun begins. This one has two separate raceways built in; at the top of the escalator is a switch to drop the marbles onto different raceways so the marbles can run both at the same time. All in all, fun to build, fun to run. And well worth the asking price too. I can happily recommend this puzzle to all my friends, that's for sure.
Nancie R.
Enjoying putting together so far amazing
Gerard J H.
Perfect Gift for our 11 year old, He got right to it. It's now a work in progress and he wants to do it on his own, as I said, the perfect gift! Service was fast and efficient, they guided from purchase to delivery.
Thank You to all involved!
Eric J.
I bought this as a Christmas gift. Shipping was fast and easy.
Connie S.
I bought some of these last year for Christmas gifts and they all loved them. So I got different ones this year for all the sons. Loved seeing them when all done.
Rebecca C.
Christmas gift for my son in law he will love it.
Darla H.
I purchased the roller coaster for a Christmas gift, so have yet to see it in action. I can say it was shipped promptly, the packaging is really good, and I can hardly wait to see it go!
Valvoda G.
My grandson loves them.
George F.
It was fun would advise to lightly sand pieces and maybe wax the parts that go into a slot. I will buy another one
Cliff B.
This is a Christmas gift. I haven’t opened it yet. It looks awesome!!
Ernie h.
I purchased this for my grandson as a birthday gift. As a 14 yr. Old he had no problem with assembly. Well made.
Dorothy V.
Very impressed with all aspects of this product. Picture directions were excellent!! Amazed at the sheets of parts so precisely shaped and fitted together perfectly. Ramps from wheel I will have to tweak a bit for a little more slope for a continuous roll--Being older with hand issues--I will check to ensure I've seated all parts correctly. Enjoyed putting this together!
Maxwell J.
It is a Christmas present.
Eddie E.
I like the product and the instructions are easy , like the way you can scan the bar code to see what your working on in action.
Will post the completed pic when I finish.
Emily
It is good experience to enjoy family time together, excellent brain and hands on exercise, love it !
joseph s.
Very well designed.
Instructions are very accurate.
And an engineer... This is great fun.
Jennifer B.
Granson had fun putting it together
DAVID E.
- Opened the box with my 6 year-old grandson and son and proceeded to build the roller coaster.
- Easy to follow instructions - the exploded views really helped.
- Took one sitting from 11:30 to 4:30 to build, I located the pieces, my grandson punched out the pieces and son put them together.
- Was surprised at how well the pieces fit together
- We talked about how well this was designed and put together.
Stanley E.
I really enjoyed putting this puzzle together, you must read the instructions carefully and make sure that you follow every step.
I will do more.
Donald P.
Wow!
I have always been fascinated by clockworks and this kit gave me a chance to build my own.
The instructions are very good and they include videos for the tricky areas. The parts are high quality laminated plywood and remove easily from their sheets. Fitment of the parts is excellent.
I made the mistake of buying only two of the roller coaster kits. I should have bought all four (fourth one free), but I'm buying them now!
Jeanne B.
We gave this to our grandson for his 6th Birthday he is having great fun building it with his Dad.
Joseph G.
As a craftsman I was intrigued by this idea. It's a fun project but challenging - takes patience and dexterity but pays off with a cool little machine. Took me a couple of days to build. It's smaller than I expected from the pictures, maybe because the metal balls are smaller than regular marbles (those won't fit the tracks). Instructions are clear (follow them, especially where gears need wax lubricant!), parts are well organized and labelled. I found that a small touch of glue in key joints helps stabilize the tracks. The action is repetitive and with small kids the novelty would wear off plus rough treatment could easily damage it. But it's a nice conversation piece and cool to look at.
Bernard R.
My son and grandson love it! It’s been hours happily putting it together, and it works fine just like in the video! Really happy with this purchase.
Quent H.
Model is about 80% complete. I'm very impressed with the precision fit of the pieces. The snug fit is tight enough to not require glue but still go together easily. I found the instructions easy to follow but I am an experienced modeler. Beginners may need to watch the online videos. I did, however, need to use a powerful magnifying glass to view some of the detail photographs. I would like to see a Harley Davison motorcycle in the near future. Quent Hudson (75 years old)
James S.
Had a lot of fun putting it together and operating it afterwards. Will be putting the climber together next. Will definitely order more.
brian s.
bought two of them, both extremely well built, and fun to build
Jeanne B.
Best assembly details I have ever seen parts fit perfectly and easy to do.
Kurt K.
Very impressed with the craftsmanship and strength of the pieces and final product once completed. It's fun and engaging for the whole family! Buying another one soon.
Rani S.
Had a very fun few hours putting this together. It is very clever. The pieces were nicely cut from good quality wood, so I had no problems with them splintering or not fitting well. To get my marble parkour to actually run once assembled took a bit of tweaking, but it runs just like the demo now. A nice kit, I highly recommend.
David B.
Completes my set of 4!!
Charles B.
These ROKR sets are superb! This was my first build and I will be back for more. I got 3 pieces in backwards and broke a couple others...easily rectified with a bit of patience and glue. I thought I had one piece that was too short to make its connection, but friends in the ROKR fan group on fb found the mistake...I hadn't fully connected previous pieces that brought everything to fit properly, as designed.
