Input: Consider Input: 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.

Output: negative

Input: Consider Input: I bought a pair of Harley-Davidson brand boots several years ago, but they were always a little too narrow and uncomfortable to wear for long periods of time. I was about to toss them into the Goodwill bin when I thought of shoe stretchers. After reading a number of reviews for various brands and types, I bought these. I followed the directions and now my boots fit perfectly. I recommend giving these stretchers a try before getting rid of $100+ leather boots or shoes that are too tight. Just be patient and follow the included instructions. I also appreciate the inclusion of a long shoehorn, all packaged in a convenient bag.
Output: positive
