Fantech 2SHE1221 Series 12 Inch Shutter Mount Exhaust Fan - High CFM Ventilation for Home, Garage, Bathroom & Commercial Use

8-year update... This dang thing is still running. Changed to 5 stars. Hope I didn't jinx it.Initial review:Reading reviews on this and other exhaust fans of this type is a frustrating experience, so I'll try to make this review as honest and clear as possible. First, I am a fairly proficient "handyman" type. I don't call repair persons unless 1) it's a plumbing issue other than clogged drain, or 2) it's an electrical issue that involves the main, or 3) it involves larger work (i.e., replacing a roof) or requires expensive, specialized tools (i.e., a backhoe or wrecking ball). I've had good luck and a lot of experience DIY-ing.This fan came out of the box fully intact and ready to be installed. The only other item in the box was something that looked painfully like an instruction booklet, which I quickly discarded. I measured the frame around the shutters (10.25" x 10.25") and used this measurement to cut the hole in the location I wanted to place the fan. I then placed the fan in the newly cut hole, facing out, and used the pre-drilled screw holes on the mounting plate of the fan to screw in 4 appropriately-sized wood screws. It held tight.I then attached a cord with a plug on one end to the black and white wires that were sticking out of the fan unit. Plugged it in, and voila, it worked, and my work was done.Pros: It is what the description said it was - Honest price (time will tell more). It's all metal. It was easy to "see" how it worked and how to install it. It appears to move quite a lot of air. It is NOT silent, but it's NOT louder than a good-working box fan. There are no vibrations that concern me, and the fan appears to be well-balanced. The shutters work as expected; they open when the fan is on, and they close when it's off; shutters are NOT air tight, and I didn't expect that.Cons: The only real negative thing for me was the 2 black and white wires sticking out of the TOP of the motor housing. Seems like they should stick out of the bottom instead. Only about 5" of wire was included. I would have like to see this feature be a bit more heavy-duty and secure. I may rewire that part myself. This was the deal-breaker for 5 stars.Since this fan was just installed, I can't vouch for it's long-term veracity. But I will edit this review if it turns out to be a dud, or if it knocks my socks off with a superior performance. Or even if it just works as planned.
