Product review (1 stars): Lambro Vent Cover
What a piece of junk! Bought this to replace a battered Deflecto vent cover at our new house (thought I was saving $10). On first impression wasn't happy about the fact that there is no guard behind the louvers so if one gets stuck open or worse, breaks off then you're screwed (thought I was saving $10). Birds, mice, whatever can get in.

Figured what the heck; I've paid for it, got it, might as well use it. After 20 minutes and some bloody knuckles and NO new vent cover on my 6" pipe, I slid the old Deflecto cover back in and came inside and ordered a new 6" Deflecto cover (that has an extra guard behind the louvers). You see, the Lambro vent cover is exactly the same size as the pipe whereas the Deflecto slides right in the 6" pipe tightly. If Lambro is trying to make it extra snug so the pipe can give a little it won't work when the pipe is in a brick wall!

Anyways, I will give it this much: I was actually hitting it so hard trying to break it with a rubber mallet or get it into the pipe one and neither of those happened. One star for not breaking.
