input:  Now, answer this question: Title: Excellent! Review: It was an off-season purchase, so I haven't been given a chance to use these goggles, but I got them for about 60% less than usual and [...] gave these goggles one of the highest reviews for ski goggles. They're comfortable on my face and easily adjustable. Is this product review negative?

input:  Now, answer this question: Title: Great Book on Hapkido! Review: As a practitioner of Hapkido for fifteen years and an Instructor for ten, I think this is a great book on Hapkido -- it really takes the reader to the essence of the art.Hapkido is such an elaborate system of self defense, I think few people really realize how impossible it is to truly illustrate this art in the form of a book. Master Scott Shaw, does just that, however. Through very clear detailed descriptions and photographs, he instructs the reader in the true self defense aspects of Hapkido.

input:  Now, answer this question: Title: Worked for a day then dumped water on the floor Review: We've been going through humidifiers trying to find a good one. I was attracted to this one because Costco sells it and we could return it for a refund if it stopped functioning at any time.Well, on day 3 it went back to costco. The ultrasonic transducer stopped functioning to produce vapor and on top of that it started leaking on the floor. Overnight it would drop the contents of the entire reservoir.I had high hopes. This would be a great unit - if it worked. Is this product review negative?
