I was pretty happy with my sunnysky x2204 motors for 5 months. But now when I started to push them stronger, a motor belle came loose and I realized that these cound be fakes!!
A very good video showing the differences:

I must say my motors looks better as the motors in the linked Video but some differences can i also notice.
