Jumped in after Kolio's recommendation on these....HTC One Mini M4 Leather Effect Skin Wrap Cover Sticker Protector NOT CASE items in smartskins store on eBay!
Free delivery, and got it within a couple of days.....only problem...i ordered the Matt Black, and received the carbon Fibre effect!
Not exactly what i wanted, but fitted anyway, as said before, very easy, and can be removed and refitted at will, went the whole hog and put the lot on, but will probably end up removing everything but the back.
Gave it all a good going over with a hairdryer as recommended and it all seems to stick very well.
I've had one of the Xtreme Guard skins on mine for months now, and apart from some discolouration to the rear skin, this has served me very well, glad i still have another set spare....
After removing the rear skin, there was not a mark on the phone, and no residue left from it either, just some gunk around the edges where it all seems to build up.....and also, once removed the thing was still as sticky as hell, i could easily have put it back in place and carried on using it. (Took a fair bit of pulling to get it off as well!)
Anyway, here is a pic of the rear carbon fibre skin that i have on now, not ideal but it will do for now, until i contact the seller and see why it was sent.
