It feels comfortable.. a much different feel compared to before. You don't feel as much heat coming from the area.. maybe its shielded.. I just put mine on a week ago.. so far so good..
I think its one of those items you either like or hate... kind of like the iskin keyboard protector..
You might get mixed reviews depending on preference..
