Product review (2 stars): Made not to last
I just installed this unit today.  The most disturbing quality issue on it is the bubble switches.  The little plastic holder was broken when I got it.  Rather than tell my installer to go home we adapted what we had with duck tape and glue.  The vent is doing well now, and the LED lights give good light.  Consumer reports rates this one very high.  It is a shame bubble switches and circuit board holder are made very flimsy,  otherwise it is a good unit.
