Input: Consider Input: I ordered 3 of these. They are sturdy, comfortable, and stay inflated. The electric motor in each easily and quickly inflates and (almost) deflates them. The height also makes them feel more like a real bed.However, if you want to completely deflate them for storage, that can be a real trick. I could never deflate any of them completely, so in frustration I cut one open to see what the problem is. A design flaw allows an internal plastic flap to cover the deflation port when they are almost empty. The more you try to vacuum or squeeze out air, the tighter the flap seals the port, sealing in the last bit of air.Now I know, and there's nothing I can do about it, but I feel better after attacking one with scissors...

Output: Negative


Input: Consider Input: Great. Gives you a pause to remember the real meaning of Christmas. Nostalgic and well loved. Without the glitz and flash of so much that modern Christmas has become. Simple and straight forward, young to old can enjoy it.

Output: Positive


Input: Consider Input: I am pretty familiar with the great jazz singers, though not a great jazz fan.A friend shared this with me and I was blown away.Now everyone has different tastes, but I have always thought Nina Simone the best. The sheer volume of Nina's work gives her an advantage in the expanse of material.But vocally, and in terms of phrasing and lyrics Gloria is also great.And yet she was contemporary more or less with most of the great jazz singers of her era, being born about 8 years after Ella Fitzgerald.Fame is fickle though and for whatever reason Gloria remains way underappreciated.I love all of her songs on this cd.In one she sings like a Buddhist about how everyone gets older, everything recedes into the past in a way that transcends most pop song ditties to say the least.It is in a class with Nina's Who Knows Where the Time Goes.


Output: Positive
