I bought the 3 pack and had no issue with the first 2. Went to use the third and it is NOT the same and didn't seal off the water. Waste of money. Only OEM for me from now on

Ex Output:
negative


Ex Input:
Omg these are the cutest and just as I imagined! They are more like a postcard rather than like a folded over card. They are perfect size and super cute!

Ex Output:
positive


Ex Input:
This has been great, the material is soft, and even with several washes, it is still great quality material. I don't use the buttons very ofter, I just raise up the whole thing, but I think it is out of habit mostly.

Ex Output:

positive
