Bad batch of motors?

I bought the Detrum BM3720A-650KV to replace the same after it got fried in a crash. They sent a "upgraded" 750kv motor. That one had a stripped thread for the prop adapter and a bad bearing. Dynam customer service was quick to respond and sent a new motor but the new motor also has a bad bearing. The motor sounds like grinding metal to metal and is very noisy.
I'd give the motor 1 star and the customer service 4 stars I gave an overall score of 2 stars. If I ever get a good motor I'll re-rate it. My old 650kv motor was excellent!
