Ex Input:
I am 82 years old and I am cleaning up a 10 room house that I have lived in since 1971 It was overwhelming especially since I came from a home where clutter was normal. This book is wonderful! The author tells me how to do it without any garbage. So now I look at the job with a very new perspective. And it works! I have hope again. It has banished my depression as I look at piles of newspapers and magazines on the kitchen table. Now I know how to deal with them. This is a wonderful book by a wonderful person. (Yes, I know. Too many wonderful's but they belong.) Buy the book and see. You do need your own copy. I think mine will get worn out with wear but I will keep it until it has been memorized.

Ex Output:
positive


Ex Input:
Buying these is like playing Russian roulette. If you get a good one, like a friend of mine's, they are well worth the price. But the one I received had parts that did not lock together and the rotor wobbled. I returned it.

Ex Output:
negative


Ex Input:
Had to throw them away. I'm not even going to try to contact the seller, after reading about the problems others have had in trying to do so. I work with my hands, so they're strong, but I can't light these without trying 10 times, and nearly using both hands. Definitely not worth it.

Ex Output:

negative
