I bought the Jelly Comb back in April. It has meh reviews now though. Attaching it was straight forward, but I could see some air pockets / haloing around the speaker grills for some time. It was outside the actual viewing area so I just ignored it. After a while, they went away and the glass just seamlessly blended in. It's been pretty good, but I just noticed a nick formed along one of the edges. I must have hit it against something. I've dropped my phone in a case about a dozen times, and it's still good otherwise.

Jelly Comb makes a good one.
