Vent closer broken when I opened the package. Not worth the hassle or the money. Sent it straight to the dumpster.

Exactly as shown. No on-off switch.

Fan works ok, but not impressed. Door vent broke during install — cheap small spring on it.

I needed this to ventilate a back room with no windows... It's pretty quiet and pulls the fumes out nicely.

I bought 2 exhaust fans for 2 locations. I’m 100% thankful to whoever came up with the idea of creating it.

Got the 4" with hopes of providing some ventilation... it's really pretty loud for what it's accomplishing.

Tried to use it to suck cool air from an old vent. Not strong enough and noisy.

Installed for laser engraver. Noise not an issue. Just wish it was smaller. Recommend.
