ROKRMarble Run Wooden Model Kits 3D Puzzle Mechanical Puzzles for Teens and Adults(Waterwheel Coaster)

absolutely loved building this. i thought i wouldn’t be able to complete it, even though i’m a big LEGO fan. i thought it was going to be difficult, yet i finished it in about a day or two. it runs super smooth with or without wax and the laser cut pieces couldn’t have been better! it came with a few extra tiny pieces too. even my cat loves watching the marbles go down the track 😭😭

This got me into model building, it's that simple.As other's have said, be a little careful with the smaller parts as they can break (but super glue fixes that.Other than that, it was just so fun to build and the end product is both gorgeous and fun to watch.PS. Not for the impatient.

A fun to build model, very precise. I stained some of the parts using water based acrylic stains to give the model more contrast. I have ordered a small electric motor from Amazon that I will install later. I will post another review when I have installed the motor with details about the motor and instructions.

It took me about 5 hours to build this- I was in no hurry. I am amazed at the precision and how well designed and constructed this is.My daughter asked if she could have it so she could one day give it to her kids saying your granddad made this. I instantly loved this idea.All of the pieces fit together with incredible precision and accuracy. I did need a spot of glue in a few places but that was just part of the fun.If you get this, and I highly recommend you do, be patient. Remove all of the pieces very slowly from the templates. If you go slow you will not break anything. The instructions are perfect. No words, just illustrations and that's all that was needed.Huge kudos to the designers of this 3-d puzzle.

If you're a hands on crafty type of person, this is a great set! Laser cut pieces were clean and I only needed to use a box cutter to take pieces out of the sheets. No glue used at all. and all pieces fit together nicely. Definitely use the wax provided liberally for the gears portions of the project. if your steps are sticky/blocked, apply more wax. Once I got things working smoothly my 5 yo has no issues turning the gears/working the steps as they should NOT be sticking. It's been over a month and haven't had to reapply any wax or anything like that.Super happy with this set an will be getting another in the future!

This is a high quality laser cut kit. The instructions are very good and clear. The pieces come free from the sheets and the supplied sandpaper makes it easy to clear the burrs. I found that a needle nose plier could be helpful at times. As I assembled I tested the marble travel and adjusted at each step. That made the final adjustment a lot easier.The laser cut is very precise which makes the whole kit a real pleasure to work with. In a nutshell this is an enjoyable kit to put together.

It's an amazing puzzle for all ages. I bought it as a gift for my husband and we put it together in about four days in sessions of about 2 hours. Now it's an eye catcher in our living room! We had a blast. This kit includes every tool and every material you'll need to put it together, so no need to buy anything on the side. It's just amazingly well done, very fun to assemble, very entertaining to play with, and on top of that it looks beautiful as a curious ornament!
