Q: 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...

A: Negative

Q: I picked up Hard Times preparing to enjoy it since Charles Dickens is my favorite author. While not going so far to say that I was disappointed,I will say that it was the first Charles Dickens novel that I almost felt like not finishing. Not only is the plot rather humorless, but the characters are charmless and almost uninteresting. If it hadnt been written by Dickens then I may have liked it better but as it was it did not have any of Dickens usual charm and humor.

A: Negative

Q: I found this book very realistic. As someone who suffers from mild mental illness, it made alot of situations real to me. I enjoy the NYC mentions as I have recently visited New York. I could visualize the book well.
