DrMotor,

I have read a number of your posts in the past. You seem to be very interested in where things are made. That is fine. But you do not cite asource for your information. How do you know these devices are made in these factories? Are there statements by the brands that you mention that their goods are made in these factories?

In fact, I really don't care which factory makes them. I only care about the features, function, reliability and overall quality of the products I receive.

It is quite possible to make several brands or products in the same factory, each to a different design and quality level. Even if 10 different ESCcome out of the same factory, that does not mean they are the same, or even similar.
