Ex Input:
I bought these to use around the house instead of carpet slippers as they were making my feet sweat, and after being in work boots all day a bit of fresh air would not go a miss.

Ex Output:
positive


Ex Input:
Look out. I’ve used these for several years and the colors are no longer red, dark blue, yellow and dark purple. I received neon green, orange, aqua blue and fuchsia pink. Dark purple was okay for my little guy, but bright pink isn’t going to work. Will either have to use one old car from last school year or order another set to have four. I put two under a yumbox and two on top in a lunchbox. Others are right about not staying cold long, but works great to keep non perishable items cold.

Ex Output:
positive


Ex Input:
Very, very disappointed. Sooooo flimsy & cheap. I have purchased pillow inserts before & they were actually like a nice uncovered pillow. These remind me of those cheap pillows you sometime are given when you're flying. I intend on returning !!!

Ex Output:

negative
