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.

This product worked for 4-5 times and the rotation stopped working. Batteries run out or lose power after 3-4 uses. I would read reviews before buying another one... I am looking into the Hitachi wand massager now and I believe I will buy it since is a power operated toy and will never run out of power.Not impressed with this product.
