A:Answer The corners do lift off. I found I have to replace mine every 2-3 months. You can register them for warranty on Zagg. They used to charge only $4.95 S & H, but when I last requested a replacement for my cracked iPhone screen, I noted the replacement warranty price increased to $10. That's ok for the iPhone screen which is more expensive to buy, but hardly worth it for the watch which costs $14.95.
