Q: Love ur products but this one is NOT good. This photo is 8 hours after class. I've had this mat about a month and the stains never completely disappear. I'm a woman and I do sweat but it's embarrassing to see the outline of my body at the end of class...to the point where people start staring at my mat and at me. Yuck. Please let me return for refund if possible.

A: negative

Q: This thing didn't even last on the phone. It wouldn't even install properly. I've put this type of screen protector on about 25-30 phones and thought I would give this one a try. Big mistake. Stay away
