Example Input: These are only meant for use as temporary or guest bedding, but I've been in a situation where I am using this item daily as my bed for over a month now. I am a large person. It has held up beautifully. I add air maybe once every 7-10 days. The flocked top is great, holding sheets in place. It is so comfortable, my back and general body pain has improved dramatically since using it! I suspect that when my permanent bed arrives, this little bed will serve long and well as guest bedding.
Example Output: Positive

Example Input: This product arrived on time and in excellent condition. These boots have a good arch and seem sturdy. They do look a little cheaper than I anticipated. The tread is great. Size runs true.
Example Output: Positive

Example Input: These wraps were not doing anything when we placed them in "hot" water. We searched the internet and found others having the same problem. The instructions are very poor. First off, you need to dip in boiling water (or at least some temperature level above what I would call hot). Second, the instructions don't describe what should happen, should the image shrink around the egg, transfer to it -- what?Needless to say, it was frustrating for a minute or two, but my wife - who is very intelligent and great in the kitchen - immediately thought, "well... hot water wouldn't do much to change the properties of the plastic, so let's try boiling water - nothing to lose."Should be more explicit in the instructions. (We were using the star wars version of this product).
Example Output:
Negative
