Review on 🤖 80Pcs Plastic Robot Gearbox Motor: Optimal Performance for Robotic Projects by Donald Vargas

Surprisingly none of these gears were suitable for mounting a small electric motor. The gears look bigger in the photo. Most gears are 1/2 inch or smaller, only a few are 1 inch. The shaft dimensions were mostly around 1 mm and did not fit the 2 mm shaft. What looks like straps in the photo is more like highly elastic rubber bands. It's useless to me.
