Was not impressed with the Invisibleshield (by ZAGG) I purchased for $19.99 and had an employee put on (for another $5)
when I purchased my ATIV S. $4.95 is still too much if you ask me.
The shield itself feels ever so slightly sticky, which on a touch screen is a big no-no for me. And after about 3 months it somehow attached itself
to a sales receipt in my pocket and pulled right off. Giving credit where credit is due though, the high-tech InvisibleSHIELD did seem to self-heal a couple of tiny nicks or scuffs it received, and some people might prefer the somewhat matted finish (reduced glare) it gives the screen.
I've been using a cheap "throw-in" shield that came with a phone case I ordered from Hong Kong. It's been on my phone for 3-4- months now and I actually prefer it....glossy "glass-like" finish, maintains very good touch response.
