Input: The gears strip too easily. Our first unit stripped after less than 1 minute of play, literally. We decided to replace it, and at least the second unit lasted about two weeks before its gears stripped too. Now we’re returning it (the replacement) for a full refund. UPDATE: about 14 months later (May 2019), we decided to risk getting a *third* one of these. Its gear stripped within 1 week of play. With one bad car, maybe we got a lemon. Two bad cars is very unlikely, but still possible. Three is astronomically unlikely. There is a manufacturing defect somewhere. We’ll be returning the third one and never buying another one of these again. The weird thing is that the other karts in this series (Mario, Bowser, Donkey Kong) don’t have this problem, or at least if they do it doesn’t appear right away (within the first two weeks). We know, because we’ve bought like 10+ of these over the last couple of years. (One of our dogs loves to play with them.) All three of the newer Yoshi models stripped their gears within two weeks, and none of the others did. Something is rotten in the Yoshi production line, something that weirdly doesn’t affect the other racers in the line.

The gears strip too easily. 3 units in a row all stripped within 2 weeks each.
