Review title: Worthless without a plug, Amazon was great as always with the return. Product review: After reading reviews where some said the plug was easily lost and other said there was no plug, I decided to carefully unbox the product in the middle of a clean living room floor so that the plug if present wouldn't get lost. I examined the contents of the box one at a time. It simply wasn't there.The pump worked fine, the material seemed thick and sturdy enough. When inflated it was dramatically smaller than the same sized ball at physical therapy. I'm guessing that the 75 CM measurement is accurate, but that consumer products are measured one way and professional products another.I'm guessing most of these actually have plugs included or Amazon would get tired of processing returns.

Question: You are considering whether to buy a product. You look at the reviews. Would the following review decrease or increase the chances of you buying the product? Review title: An Outdated Book for the Rich and Healthy Product review: An interesting book, but really only workable if you have $400K--$500K in assets. What's worse, Terhorst assumes you'd be living off the interest generated by investing your assets in CDs earning a currently unheard of 8% interest.In addition, the book doesn't touch on health insurance. I'm guessing that when he wrote the book almost 15 years ago, health insurance was far more affordable than it is now. Either that, or he was assuming that you could self-insure if your assets were so high.I'd like to see this book updated for the 21st century--i.e. how to "live off your assets" when interests rates are 2% or less, and how to live on "$50 a day" (Terhorst's mantra) while still securing health care.

Review title: pretty awful Product review: I usually enjoy Mary Daheim's books. They are improbable but entertaining. This one is beyond the pale. Judith intrudes on a police investigation without reason or invitation. She invites the woman who stole her fiance, leaving her pregnant and with no alternative than the awful Dan, and that's just the beginning. I lost all sympathy for the doormat, and her investigations annoyed me. I ended up giving the book away.
