Solid kit, just follow instructions closelyThis was my second ROKR marble machine to assemble and it assembled well just follow instructions.I knocked it one star as the motion on this model is focused on the lift and just one marble at a time moves which makes it a less action packed compared to the Marble Parlour which has many marbles in play at once.

Looks absolutely awesome fun to put together

This is Awesome!This product is very fun to build.. the precision cut for the parts are on point.. However, you still need to be careful as there is a slight chance of breaking it.. not all parts has a spare.. Smoothing the breakoff section of each part is recommended..The manual crank is ok.. hope they have an option to include motor to have a motorized version..

Fun to make, fun to use. Now what I want is to somehow put in some chimes or bells so it can ring as the marbles go down.

Mind you, haven't built it yet: it's a Christmas Present for myself. But I already own two of the other Marble Machines, and they keep getting better. . . .(and I also have improved my construction techniques!)

Olichnik designer, everything is clear, there are spare parts even, collected three several hours and everyone liked it. Prices are cheaper compared to ugears, but the quality is even better. Definitely only this designer to take!

This was a great Christmas present for my friends kid. I don't know if they like it.

The order came intact, the box, though, a little crumpled, but inside everything is whole. We have to collect. Let's see how it works.

Very fast shipping and the product looks great. Thank you!

Not the best laser cut puzzle.

A couple wooden pieces were warped severely. I had to boil water and place these pieces into the water for about a minute to soften the wood, then I placed these pieces on a flat table and used a clamp till they dried. It worked out to my satisfaction. Also there were a few laser cuts that had to be modified to make them fit using a small file to make some of the cuts that were connecting to another piece a bit deeper. But considering they were made in China, I guess I should be satisfied.
