Zerp 2 Yes, the ad does say don’t swim or exercise with the watch on because water can get under the screen protector. That is not only an understatement, but an effort to minimize a severe problem with a poorly designed product. First, you have to remember these watches are meant to be worn when exercising. I saw that, and have no intention of working out, so fine. But taking the dog for a walk on a sunny day? Well, you’re going to sweat. Apparently I wasn’t careful enough and a drip of sweat got on my watch. You can see the result in the photo.And with the pandemic you need to wash your hands frequently. You better plan on taking the watch off every time you wash your hands because if a single drop of water gets on the watch then you have to remove the case and clean the it. This is not a simple task because smudges and dust will show if you put the case back less than perfectly clean.The case was poorly designed. The manufacturer discovered that the screen protector was not fully sealed and the smallest amount of water would get under the screen. So their solution was to say ‘Don’t swim or exercise with the watch on.’On the positive side, the case goes on nicely. And it doesn’t detract from the appearance of the Apple watch. But to be useful? They would have to provide a pack of 6 in a carrying case so you could change the cover every time a drop of water or sweat hit the cover.No, this is a useless piece of garbage.
