Q: Okay, let's face it, it's all about time and there's just too little of it. With this cookbook, not only can you recapture some of that time but you can also serve up some absolutely scrumptious meals and snacks. I know the purists all rave about the use of packaged prepared foods, but come on, who today has time to cook from scratch? Statistics prove that fewer people cook from scratch and get bland, pedestrian fast food, with Semi Homemade Cooking anyone can be a ten minute maestro of the kitchen.

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
