Grrr....
I got the second Shield Zone in the post today. Spent an age over installation and following my previous experience applied a good dose of liquid before applying. The only problem is that I checked back after an hour or so to see a hair underneath! I couldn't see it before. It must have been an eyebrow hair that dropped on when I was doing the installation.
So, lifted up the shield carefully and tried to get it off. No dice - couldn't remove it. Eventually made a real mess of the shield so had to throw it away - again!
Shield Zone being so expensive here I've now spent about $50 and my screen still isn't protected.
Have purchased a cheaper brand off eBay to try out so we'll see how I get on with that...
