Example Input: This plaque is a very thin piece of cheap wood. The lettering is sometimes hard to read. Very disappointing and too embarrassing to give as the gift I had planned.
Example Output: negative

Example Input: My best friend got this mattress before summer started and I've slept on it many times and I get the best sleep at her house. I asked for the mattress as a birthday present, I opened it on the 9th and as I was unrolling it i was starting to smell something musty but i thought it could be because it just traveled in a box for a few days. It's now the 12th and my ENTIRE BOTTOM FLOOR WREAKS OF SOME NASTY MUSTY SMELL. It smells like the bed is rotting. OH and the mattress I ordered is classified as a 6inch mattress but its measuring between 4 and 4 1/2 inches... 3 days later. Today is the first day I have done anything other than touch with my fingers or sniff. The bed feels very firm and if you sniff it you will want to gag. I've already filed through amazon that I'd like a replacement. I'm just puzzled how the mattresses could be so different. We both slept on her brand new, 6 inch, Zinus mattress less than 24 hours after she opened it but mine is like I picked it up off the side of the road. When I get the new mattress I'll edit my review accordingly.
Example Output: negative

Example Input: I have been looking for a bike bag in order to have my phone available, water bottles, and to store just a few things. This bag came with 3 velcro straps, securing it without jostling as I ride. THe others I looked at were more expensive and didn't have this feature. The "cone" down makes it compact instead of a large " box" on the front. Aesthetically attractive!! I HIGHLY recommend this product. Almost forgot, the clear pouch at the top is great for maps, seeing calls, and let's not forget the safety - hard to steal, makes it available for calls in case of an emergency, just a very handy feature
Example Output:
positive
