[EX Q]: I purchased this airbed because I wanted to sleep in the same room as my newborn. Yes, I'm one of those paranoid new moms. This bed goes above and beyond. I wanted to buy the AeroBed first because I'm one of those people who hates to buy cheaper items because they usually break or whatever. I'm pretty much a sucker for the theory that expensive = quality. However, I went with my gut and decided to try this airbed having never heard of the company before. Listen to your gut! It inflates in 3 minutes and deflates in about 3 minutes. If you want it to be more firm & allow the air to settle in better, you should leave it in there for about 7-10min. Not a big deal at all. Go do something in another room while you're inflating it. This thing can also handle a lot of weight. When I'm sleeping on the airbed, my husband comes in the room to tell me he wants to sleep in this bed too because it's so comfy. Great Buy!
[EX A]: Positive

[EX Q]: The title of this video mentions Argentine Tango. Unfortunately, what is being taught on this tape is not authentic Argentine Tango. Not even close. It's ballroom tango. There is a huge difference: in music, style, steps, posture, etc... Don't be fooled by ballroom instructors trying to teach Argentine Tango. The only authentic instruction available on the market comes from authentic Argentine instructors from Buenos Aires.
[EX A]: Negative

[EX Q]: Somebody from higher places should have stopped Mr. Higgins and the publisher from putting this book on the market.Its quite disturbing to see the absence of integrity and sense of responsibility in providing a joy of reading to the public.All along, I had fight off the growing urge of disposing this disastrous novel only because the shipping charge cost more than the book itself.Yet, once I overcame my frustration and finished the book, I regretted not heeding to my senses.Its obvious that Mr. Higgins had no heart in writing this book, and he made no effort in showing creativity with words.I was about to scream my head off when he kept rehashing the same phrases (e.g., browning with carswell silencer) over and over again in every single chapter!!This book made me a true anti-Higgins....
