I just wanted a simple, good looking case with the sleep function, and that's what i got to be quite honest. This could have been a great cover had it been made for the new ipad 3 as advertised. Instead, the sleep/wake function doesn't work when you close the cover. Also, even though I went in and out of this case several times, there is a chemical smell. Not sure if it's from manufacturing or shipping. Will do some touch-up work, but overall the picture looks great.

When I bought this book I was expecting more information. Most of it I've had heard before and could find very easily at the library. There are a few helpful tips, but overall, not worth paying for it! Unless you're someone who knows absolutely nothing about getting older, then maybe it's worthy - to save you some money. It only takes me 10 min to write my thoughts on every topic in the book.

Ex Output:
Good Review

So much for the good idea of a stainless steel can with no plastic! I was disappointed to learn that after being in use less than ten times, this plastic had begun showing and chipping on every can. It wasn't an issue before, but now it's getting worse at the seams between top handle and lid handle. Looks very bad under use. A friend told me about rubber bands used as handles. I'm glad Amazon has them because replacing it is cost prohibitive.
