Nice

enjoyed by boy who put it together

Grandson worked on this until he finished it all!! He absolutely loved it!!

I bought this for my 8 year old grandson. It has a ton of minute little pieces and needs to be separated and put into little bags ahead of time. This is a huge job and definitely not on an 8 year old level as advertized. It is very difficult to build, and even my engineer son had some difficulty. The solar-powered motor works, but that is how far we got after a whole day's trying. We finally gave up. I'm sure older children may have fun with it.

Shipping was super fast, can't wait for "build" day.

Move on. This one is a dud.I have read a lot of reviews of products and decided not to buy them based on the review. As a result, I think I have avoided buying a lot of junk. This one must have slipped by though so now it's my turn to warn others. I honestly don't know why the others rate this so highly; I expect the parents are doing all the work and then handing the toy to their child.Even if this toy met expectations, it would NOT be suitable for kids younger than about 10 years old.The directions contain a 1:1 diagram (sounds good) but the diagram is not the same size (1:1) as the parts (very bad). Contains 190 pieces (sounds great), but you have to cut them all out AND THEN remove the extra sprues with the included nail file (now you too can do factory labor in the comfort of your own home!). Basically, they were just trying to save money by having the user do the work that should have been done at the factory.The instructions look like they would work (super!), but they do not (lame). The gear assembly requires several hands to hold it all together while getting all the pieces in the right place. Many of the axles have multiple stops on them where the washer can be placed to push the gear into the right position, however the directions do not state which stop the washer should be placed at. You can see how some of the parts are SUPPOSED to work, but they are not quite a good enough fit to perform as intended.As others have mentioned, many of the parts look the same, so it's easy to confuse them. There are different colors of plastic, which could have been used to differentiate between parts (a great idea), but instead the similar-looking parts are the same color as well (poorly executed).Yes, it's fun to watch the gears go around when the solar panel is placed in light, but no it is not fun to find that the parts do not go together as described.
