So far I haven't had problems either, but have been told they fail prematurely. I have had different experiences with the keep on, it always performs the way I want and the bearing is fine. Any ceramic bearing will go if overheated, and I'm still learning that fine line between perfectly tuned and too hot. I have 2 keep on motors and for as long as I can get my hands on them, I will be running them.
I do want to try the virtus 12 eventually, just have no reason to replace what I have for now.
