It takes a bit of effort to get off, very snug fit. You could probably loosen it up at bit with a hair dryer/heat gun before you put it on the phone, but stock it's a bit snug. I'm demo'ing the H815 so it's not a daily driver, just a home jockey and it came with the stock film on it. A real screen protector might take up a little more room but even so I think the lip will be generous. I should get my VZ phone from the store this weekend and I'll install one of their screen protectors, I'll post feedback as soon as it happens.
I'm a thin case person and it doesn't get much thinner than this...my kind of case! I'll keep my eyes open for alternatives though before I settle on a permanent version. It's cheap however, I was just going to deep six it if I didn't like it, not sure if they lip will get on my nerves or not...I'll follow up on that when appropriate.
