Wood Trick Wooden Marble Run Electric Motorized - 3D Wooden Puzzles for Adults and Kids to Build - 15x14 in - Roller Coaster Wooden Model Kits for Adults and Teens to Build

Me ha gustado mucho la precisión del tamaño para lograr un ensamblado muy ajustado. Producto muy divertido de montar y de utilizar una vez terminado.

My first Woodtrick puzzle. Easier to remove parts compared to other brands. Took longer than I expected, but well worth the effort. Works great after some minor tweaking. Many spare parts…if you break a part, check the spare parts sheet (it takes up more than half of sheet #9!) before you get the glue out. The wiring diagram is not complete. The manual only shows the motor white wire to the switch white wire. The rest is red to red from the switch to the battery box, and green to black from the motor to the battery box. Also, pay special attention as to when to flip the sections over before proceeding with assembly, it is not indicated as others do. And follow the arrows. The manual is large and shows where to find the parts. Past experience with these puzzles is a must. Would highly recommend. Sit back and enjoy the finished product and watch it work!

Loved this wood trick model. The best yet from this brand.

I rarely write reviews but this defiantly warranted the time. This is an excellent model, but not for the faint hearted. Patients is defiantly the buzz word and lots of it. Some of the pieces can be tricky to remove from the board and care is needed not to break them. Coming from an engineering background I can appreciate the work that has gone into producing this model and I must say the Laser cutting accuracy is astonishing. Top tips: dispense with the silly little piece of sandpaper supplied and 'borrow' your wife's emery board she uses for her nails, far easier to use for the fettling jobs. For parts that have multiple location pegs, file a small chamfer on all corners of the pegs to aid location. A fair bit of force is required to locate pegs so I found a pair of long nosed jewelry pliers very useful to apply pressure in the right places. If you require glue,then something is wrong. Finally, one (and only one) small quibble, is that I found that the base board between the motor unit and the large wheel to be a little too flexible thus allowing the pinion gear to come out of mesh with the large gear under load. Sorted this by gluing (sorry) a small reinforcing strip across the base (Photo).

J’ai adoré monter ce puzzle, il fonctionne à merveille, je les colorier et c’est encore mieux
