I just got an upgraded model they have with 2.5" inlets - haven't had it long enough to know how much improvement.
Every model seems to be different (which may not be real) - but the one I was looking at showed 184 CFM. Whether it's much better than a CT15 I can't say - but more to the point, why spend twice as much for something at best equivalent, if not marginally worse?
Agree!
