Flaps do not stay in place over openings. I got up from dinner and my bra was hanging out.

The openings for the cards are too tight and tear when you are either trying to get them out or putting them back in.  It is okay if you don't plan on removing the cards.

This was for replacement in an older aluminum wall door.  The tabs that are supposed to hold in the flap are not as thick as the originals
so after replacing this and the dogs going in and out a few times, I looked up to see that there was a hole in my wall where there should
be a flap!!

My husband fixed this by pinching the frame in just a bit to hold the flap tighter.

The little flaps constantly pop out when I don't want them too. Other than that it's a handy little gadget.

It's protective but the little flaps are constantly hanging loose. We are always trying to tuck them back in. Overall fine but I wouldn't purchase again.

The flaps don't seem to work as well as a single flap door. But works well enough for dog to use. Rain does get in between the flaps so I can't recommend if you are installing between house and outside. I use for between screen porch and outside so it's fine for me.

They could put the flaps to open the short way not long so it is easier to use for me. I want to find the ones that were rubber with openings on top and one end. Anyone seen them?

I purchase this for a 2018 Honda CR-V.  Overall construction isn't bad given the price.  It's approximately half the cost of what the dealership wanted me to pay for an OEM cover.  The issue is the gap between the cover and the rear door is roughly 4-5 inches.  Compounding this issue is that the flap at the end droops quite a bit.  As a result roughly 1/3 of the cargo area is exposed.  The extra bit of material used to cover the gap between the rear seats and the cover is clever.  But I discovered that you could recline the seats slightly to close the gap making it unnecessary.

Works OK however magnets do not keep the flap in place reliably - shouldn't be a problem in like an interior door but these are definitely not intended to block any kind of weather - which begs the question of what these doors are really for.

The rear flap catches on my shirt collar. Have not used much so far.

Fits the hole but doesn't open fully with the ductwork I have.  There is a single flapper that needs LOTS of clearance.

I have to replace this flap every 4 years due to extreme shinkage. When new, it fits securely on warm days but shrinks in cold weather and the magnet does not hold, therefore letting in the cold air.

This bag is cute, but the flap curls up at the corners and the buckle-apparatus used to hold the strap when adjusted comes undone. The strap then goes into it's longest mode, which is way too long. Just started happening recently (and I have only used it maybe five times), so now I can't return it at Amazon for the full price... bummed as I would call this a defect.

Tight fit at first, the cover flap didn't like to stay closed. I had to spend some time stretching it.

Pickup holes were not fully sized for pickup covers to slide through.  I had to enlarge the openings to allow the pickup covers to slide through.

I guess I'm OCD, I would like it to fit better, my escape artist can not get out, but it droops in the middle and does not fit securely over corners as I would prefer

These windscreens don't easily fit over the microphone that I use.  They also tear easily.  I will not purchase these again.
