Really good kit - better than buying your own materials
I made bristlebots with my Sparks group using a combination of dollar store toothbrushes and parts from an electronic shop, but the toothbrushes had curved backs with little ridges, and the motor wires need to be stripped (hard to pull off for six-year-olds!). It was really fussy. Since that didn't go so well, I decided to order this kit to see if it would be easier for my 6-year-old to assemble. It was. I highly recommend getting this kit instead of sourcing the components yourself. My only criticism is that the double-sided tape did not stick at all to the googley eyes, so those needed to be attached with a different adhesive. The age rating is overly conservative in my mind; these can be made by 6-year-olds with a parent providing a bit of direction. The kids love the end product too.
