Ex Input:
Just received these in the mail today. They are really soft and comfortable. I ordered a M. I'm 5' and approximately 120 pounds. It's a little loose but they are comfortable for sleeping. In my opinion the material quality is very good. Not thin at all.

Ex Output:
positive

Ex Input:
Had to return it several times for a close enough fit. A size XXX is actually a large adult size and medium fit around the arm/shoulder area. Finally gave up and got a full refund.

Ex Output:
negative

Ex Input:
I bought it to save a few dollars. It was my mistake. It didn't stick well and I would be able to take it off very easily once it is applied. Do yourself a favor and spend a few more dollars and get a high rated one with over 500 reviews. I can't even return this item. Wasted money.

Ex Output:
negative
