the tinskin fits easily on to my iphone 4s,and looks very neat. it actually looks like a part of the phone rather than an extension. I combined this along with mediadevils screen protectors and have to say ,I cant find a fault . i like the fact i can use my heavy duty protector while at work as i work in a dirty environment ,then come weekend or holiday ect,i can put this tin skin on for a touch of class. that's what it is CLASS. well done mediadevil.
