Thought you'd never ask.. Rofl. At the risk of sounding like a paid agent ... I'll say go with Bestskinsever (you might have just missed out on a BOGO offer.. Check their site )
I used it from day 1 almost on my Mac n it was brilliant. It's still on my Mac with no loss of adhesion or tears or any yellow discolouration and absolutely no peeling whatsoever. Been over a year now. You can find my thread on the forums where I posted pics of it. Sold another one to a fellow member as well.
Last month I ordered and am using it with my iPad mini. This Black Friday I ordered one for my iPhone 6S which is on it's way to Bombay as we speak [emoji4]
I've used Zagg invisible shield way back for my 3G n 4 n even iCarbons for my 5 but I really loved the bestskinever wraps by far. The others don't even come close in quality
