My 11 year old grandson really liked this. Challenging and very much appreciated.

Purchase this for my son’s birthday. Kid had so much fun. Great value for the money.

12 year old grandson loved it! Many hours of creativity for him.

The original i received had a faulty led and processor but it was very promptly replaced with one that worked. The parts are extremely fragile. For example, my 8 year old brother broke the fan blades without hardly touching them. The parts are also a bit inconsistent from box to box so colors don’t necessarily match pictures or instructions, and for example the caster i got in the second box did not fit nearly as well as the replacement one - i had to glue it to make it work. The instructions also had at least one error where the connection is labeled backwards for the alarm bell. Overall, creative idea and very illuminating to a child at that age group on the working principles in automated devices, however, there are some serious quality and consistency concerns that should not be, in my opinion, considering the pricing. My last critique is that framing can be a pain to assemble and could probably be replaced by something with less annoying screws.

Why did you pick this product vs others?:It has great ideas, it shows how things are done rather than just giving an RC toy to the kid. But instruction is outdated and not clear enough for a 8-12 years old kid. It doesn't provide any useful information on what they are doing to make it a learning kit (probably give ideas on how to be creative with the kid). Components didn't have any good spot to be screwed in and felt they are loosely attached while screws were all the way in.I'd do to changes to make this a 5 star product.Change the instruction.Chnage the main board from screws to snap-in so Components could be attached easier and quicker (rather than unnecessary long screws and bolts)

No.complaints!

Would not buy again. Naming implies you can build 10 different kits, but instructions and parts are really one-use. The female jumper ends are such low quality that after a couple of uses, they no longer make reliable connections... they wobble badly. The tiny machine screw parts are REALLY tiny...need strong lighting and magnifying lens glasses to handle. The supplied tiny flat tip screwdrive is useless with the tiny philips head screws. Would not have been a good value at half the price. Never again.

Great concept, but screws are very small and bigger fingers can not control them.
