A motor failed on one wheel of my Midea robot. Ordered entire wheel assembly with motor from here and it arrived in really short time of roughly 2 weeks from China to EU, installed it without any problems, just straight drop in replacing the old one. And the robot is already working perfectly again. Excellent service and from the looks of it also quality parts. Excellent service. Hopefully I won't need it again, but if I will, I know where to shop again :)
