I bought ten of these and helped a group of 9-year-olds assemble them. The exercise was a success, but not perfect. Positives: * Good value for the price; cheap enough to give away as party favors * The cup + eyes actually offered enough flexibility for each kid to be able to personalize their robot. One child put the two eyes vertically instead of horizontally; many others opted for the "cyclops" look. * Each one worked; no missing or broken pieces in the kits * No soldering was necessary * Assembly was straightforward, even with Chinese-only instructions Negatives: * This is is no way a "line-following" or "obstacle avoidance" robot. The drive wheels are attached to a differential that randomly (chaotically?) switches between moving "forward" and turning. It's amusing, but don't expect any sort of deliberate behavior. The kids were a little frustrated when we tried a "robot race." * The alligator clips were difficult to operate: the plastic coverings were too slippery for little (or adult) hands to effectively grip to open * Many of the little yellow paper cups had been partially crushed in transit * No AA battery was included; these need to be bought separately * Since all major joints were made with double-sided foam, these are not likely to hold together well over time. For our application, this was fine, however.
