I'm using an Ultra Nano Clear, but I don't like the fact it doesn't reach the sides and I'm intending to order a Curved Crystal eventually. On a positive, and perhaps negative note, while I was at a drifting day last weekend there was a lot of dust/sand being flicked up and I managed to get a HUGE scratch on the screen. In a way I'm grateful that it's the protector and not the phone itself, but I can't help but think the damage wouldn't have been anywhere near as severe if it didn't have the protector. Overall I like it, it's very clear, becomes very smooth after being used for a while, it's not had any issues staying stuck down in the month-odd I've had it. Will wait until it's unbareable and then order a curved crystal I think, just hoping that won't scratch as easy.
