Well I bought two packs and I'm pretty happy. My first try was a complete failure as I tried to put it on in my family room with all of the windows open on a breezy day. Needless to say, all kinds of stuff trapped between the screen and the protector. So for my second try, I took some advice I had read somewhere here in the past about steaming up the bathroom and putting it on in there. That worked fantastic. I was able to get the protector on with no dust or air trapped under it. The fit was excellent.
The protector itself is not the same brand which came with the TP2, but I would say it's about the same quality in my opinion. It has a smooth feel, not rubbery which I hate, the finger and stylus response is very good, and it is nice and clear. So I screwed up one, but have four left for future use. Overall, I think my $10 was well spent.
