The life of this toy wasnt very long maybe three months with moderate use but my kid enjoyed it together

Bought this for my 7 year old since my husband wanted a project they could do together. He needed help with most of the steps (which I expected since it's above his age level) but he had a fun time and it's asking for more Kiwi kits. I would say my biggest criticism is that the wires do not stay in the bread board very well so you need to be very careful about making sure everything is in place before screwing the case together. The crank handle was a bit difficult to push all the way on the motor, but otherwise no other issues with putting the flashlight together. Very clear instructions. And i would agree with another comment that said a single piece of sticky foam for the window probably would have been easier to use.

The booklet that came with the flashlight explained everything really well - like what's a capacitor? Make more like this!!!
