1) Stopped working after 2-3 times of testing (luckily, before installing...)<br />2) when working - NOISY.  hum comes from motor.  Vortex is much quieter (apples to apples) for example.<br />3) built in speed adjustment is a joke;  90% of the turn, id does nothing, and then in a matter of a few degrees it reduces the speed from max to a little less --&#62; impossible almost to get a desired speed. also, motor hum when not in 100% is much stronger.<br /><br />Replaced with Vortex, and it just works.
