Wood Trick Wooden Marble Run Spiral 3D Puzzle for Adults and Children to Build - Electric Drive - Wooden Roller Coaster Model Kits for Adults and Teenagers to Build

Had some trouble putting it together. Had to sand a lot of pieces. Marbles come off in wrong places sometimes.

Interesting build good fun needs a bit of fiddle time to get it running properly but very injoying build Pete

Not has good as the others and broke one or two bits with my ciumsy hands, when switched on first time it worked then jammed and snapped a few of the delicate pieces Did not get replacements free as advertised paid over £20 pounds for a sheet, but most was shipping . Did a temporary repair and now it’s running ok but is very very fragile and after all my review I’m glad I bought it Denis B

Gives hours of amusement.

If you like building Lego kits or puzzles you might enjoy building this Wood Trick wooden marble run. I’m not sure this could be built in the 8 hrs quoted; I have just been doing 4 pages of the instructions each time I come home from work. With a total of 558 pieces and 94 pages of instructions, this Will take me some time. So far, I haven’t had many problems following the instructions, but removing the wood pieces is a slow process just to make sure I don't break any pieces. Also pushing the joints together during assembly can require some pressure, again making sure not to break anything. I haven’t completely finished as yet, so far there hasn’t been anything broken or missing unlike some other kits I’ve had. In places it's quite fiddly but that’s what make it enjoyable. When it’s finished, it will go in my display cabinet. I will post the final picture and video on a review update. Overall, if you like kit building this is an enjoyable kit to build. I really like the electrical motor integration to make this a working piece. I hope you find my review helpful

Very tricky to build. It took a long time to snap the parts out without breaking them. Pretty painful on the fingers. This will take at least a week to 10 days to build. Mechanism isn’t that smooth, lift shafts are getting stuck and ruining the whole thing.

Wood Trick is new to me but deserves to be much better known, if this motorised roller coaster marble run is anything to go by. There’s a great deal more to this construction than you might imagine. It’s non-trivial and likely to be as much of a challenge for adults as older children. The result of the build looks terrific and of course then you can have fun with it. The kit is a weighty item of undoubted quality. The pieces are perfectly cut and go together precisely, without glue. Many of them are very small and fragile, though, so care is needed in extracting them from the boards. The instructions are excellent – detailed and accurate. They make the task straightforward enough, as long as care and time are taken. The kit would keep most people occupied for best part of a day, longer if you choose to paint it, with tremendous satisfaction on completing it. I spent a day on this, working with my 13-year-old grandson. Not once was he distracted by anything electronic. The kit would make a wonderful gift for the right person, but given the £79.90 price you have to be confident that it really IS the right person.

Have built nearly all of this marble runs, but have to say that not impressed with this one, given up trying to get it to work
