So far it looks like they are working well. We have two packages and it is strange that one has more air bubbles than the other. It can also be a bit tricky to put the phone in a pocket as the inside sticks to the phone and it can't slip inside. This may require some maneuvering. We have not yet carried out the recommended water test to check the water resistance. I think this will do the trick, but basically it's fine.
