My last cover was one of those "full cover" ones and I had water constantly get stuck on it and had to take it off scratching my watch in the process :( Instead I opted for this style where the bumper and the tpu glass protector are separated. This way water never gets in and you don't have to constantly remove the whole thing to clean out any dirt that gets trapped.Knocking down 1 star because there's still a few annoying bubbles on the edges I never managed to get out but is fine otherwise.
