Went ahead and bought myself one as I'm tired of the sh*** glass protectors that don't work worth a damn and didn't want to mess with a wet install protector.
My initial thoughts on this are that it's really quite nice. Quality seems extremely high and the feel is also nice. I tried the s-pen on it and it left the faintest of tracks but they almost instantly dissipated. I'm not sure you should spend $40 on it like I did, but I got impatient and didn't want to wait to have one from eBay shipped. Overall pretty happy
