Example Input: Easy to use....Great product! Works great! No issues.. It heats up in about 30 mins..And works good. Love the retractable cord.
Example Output: Good Review

Example Input: It takes a lot of strength to take my vitamins with all the pills and liquid. I just bought this at CVS in their vitamin section. It's more than twice the cost. The taste is pretty bad. Maybe some people like it, but it does not appeal to me personally. I've also lost faith that anything good or natural will actually work for me. I'm going back to pills. You may love these, though, if you are one for chemical concoctions. Or maybe a multivitamin. This ain't it.
Example Output: Bad review

Example Input: After putting it on and seeing what a pain installation was, I thought I'd give the matte version a try. But it looks terrible, even with brightness at all levels (it's way too dark to see anything with this on, and bright is just as awful). Just go for glossy screens, or don't get it.
Example Output:
Bad review
