Product review (4 stars): Good simple unit, a little difficult to install.
I purchased this to replace a failed DACOR RV30 that had a blown circuit board. Since it was to replace another unit, this unit needed to fit into the hole in the granite counter top that already existed. To product and instructions assume you are installing and cutting a new hole in the counter top. The Broan unit was about an inch narrower than the existing hole, allowing it to fall through. I cut up some wood to frame it up underneath and support the unit from inside the cabinet. Since the duct work is underneath you have to mount on the sides of the unit where the power cord gets in the way. The installation instructions don't offer any help on how the mounting brackets should be installed. The duct connection is also rigid, making it difficult to mate with existing duct work. The manufacturer should not assume the unit will be a new installation. Adjustable mounting top brackets, cosmetic valences and flexible duct connectors would have been nice. I used this with the existing DACOR REMP3 remote blower which worked well; on/off and speed controls work fine. I get the feeling many of the fancier units out there fail because of blown circuit boards. I like this unit because it is simple. It doesn not have a circuit board and uses only simple switches and the motor to operate.
