Hi all new to iMore just wanted to get my fellow iPhone users opinion on the Zagg invisishield screen protectors, I have loved them since I got one for my 4S , and there warranty process is fantastic .... But just the other my poor 4S slipped out of my hand and cracked a (very annoying) but small section of my screen. With the invisi shield just hanging off any comments or similar experiences would be interesting to hear ????
