+ Pieces are well made, feel like Lego quality or better, and fit together snugly, come apart well/ durable
+ Robot works, fast, fun to play with after being built
+ Fun to see it all come together, and the way they made the treads is vert neat (36 pieces on each side that snap together well)
Cons:
- Instructions could be better. Some pieces weren't identifiable from the instructions. Some of the steps should have been reversed/ should be re-arranged. The 'rockets' have to be assembled in reverse order, or they can't be put together.
- The remote control works upside down (buttons down). The controls (up down, left right) are reversed if you use it upright.
-The robot works great on tile. On carpet it will fall over when you stop, because it's a bit top heavy, but doesn't on tile.
Be forewarned it is a bit time consuming- just look at the number of parts. If I were to do it again, I would assemble the first part to get the first gears on it, then the last part, to get the treads on it, so you can actually play with it, then go through and do the rest of the aestetic portions of it.
It's a cool Lego like project, and you can have a reasonably durable remote control robot afterwards. My nephew (9yrs old) was engrossed with it, and really wanted to see it all put together.
Get it if you're looking for a fun, intricate, well made Lego-like project that you can drive around after you build it!
