I don't know why people hate to try out schulze...
I feared them at first( I had the U-Force75 and I have the 149.18), but they turned out to be very reliable and stay cool even after harsh usage.

Probably the " loose connection" thingy has something to do with their performance.

Eversince I've hardwired the controller to the motor, the thing never went hot or made any crazy cogging.

Probably you might want to give them a try.
