I also noticed that it does not properly fit into the AC vent on my Chevy sedan

I give it a four cause I can’t really review it, it wouldn’t fit on my ac vents, but it seems like a very sturdy product that would work great with the right size vents!

I guess it depends on your car and AC vent, but in my 2012 Honda the device pulls my AC vent almost all the way down and blocks the flow of air coming out.

Stays nice and firm on my ac vent .

As an a/c vent car mount, it is very strong and reliable
