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:
This cookbook isn't simple, as claimed. I bought it for the photos and supposed ease of recipes, but the truth is most of the stuff in there is flavorless and more difficult than necessary. The most frustrating part, aside from it not being recipes most people really eat, is that the 'simple' recipes require having other recipes made before-hand, and then lists them as an ingredient. I sent it back.

Ex Output:
negative

Ex Input:
I wouldn't recommend this kit. First of all, it doesn't come with enough bags to put the beads in. The chart symbols are almost impossible to see - I had to get out a magnifying glass (seriously). Also, it's very difficult to tell the difference between some of the symbols. Some of the beads are different sizes so they get stuck in the tray. Need I say any more!

Ex Output:
negative
