The first thing I noticed is how sleek and low-profile the grill looks. It’s only about 8 inches square, so it blends nicely into the ceiling without drawing too much attention.
Once installed, the 70 CFM fan kicks in quietly, even when I turn the heat lamps on full blast. Speaking of heat, I tested it with a couple of 250-watt infrared bulbs (not included), and the warm air circulated nicely without any weird smells lingering.
The housing feels solid, and the adjustable hanging brackets made installation straightforward, even in my tricky ceiling space. I appreciated the backdraft damper too—it keeps the cold air out when not in use.

That said, keep in mind that the infrared lamps are not included, so you’ll need to buy those separately. Also, the fan’s power is sufficient for moderate use but might struggle in larger or heavily humid spaces.
