Product review (2 stars): It BLOWS! (& not the good kind)
Got mine as warehouse deal missing the hardware but thats just 5 screws, and wire nuts so wasn't an issue.  Looks good and easy to install with no vent needed , but that is as far as this thing goes. The blower motor has less power on high than a  99 cent rubber band airplane.  Was for a rental return so cheap amd fill the hole is more important than performance. If that's all your trying to do too then it will do on a tight budget.  If you cook and need a decent exhaust fan don't buy it.
