Product review (5 stars): This sucks (in a great way!)
excellent high volume cage fan. dual filter, solid construction.  Lights could be LED rather than halogen - we replaced ours with with LED and the low setting flickers (because the switch was made for halogen).  The halogens were too hot and inefficient.  We are happy to run the LED lights with just the on and off options.  The control knobs are a bit flimsy - we had one crack and have glued it (but you can't see it since it's under the hood.)  It's a nice vent that could be made much better but for the price I'm satisfied.
