You have to disable 'hands free' mode if you want to use it with a computer (which disables the microphone), otherwise the sound quality is unacceptably bad. The microphone feature was not that important for me so I am giving this 4 stars, since it works very well as wireless headphones.

I'm watching the infomercial for this product right now. Host Jim is raving about how this product cured his joint inflammation pain. Sounded great--I have a ton of joint pain. Checked Amazon, and surprise--ALL of the four- and five-star reviews are for one or two products at most. I'm not spending a cent on this scam.

I work out about 3 times a week, and usually include about 5-10 minutes of ab exercises. In investigating this product, I found that the research done on it (University of Wisconsin and a college in Ireland) showed that when used 5 times per week for 40 minutes each time, it improved strength about as much as 5X 5-minutes of crunches. The research was conducted, however, using people who had been doing no exercise whatsoever. This product seems to be designed for the bedridden or people with back problems, to give them an option for ab exercising that they wouldn't have otherwise. I experienced no ab soreness at all after using it at 80 (maximum is 99) for 40 minutes. I did find, though, that if I use it at 99 for an hour at a time on a couple consecutive days, I do feel some soreness. The experience is intense, but not unpleasant, so I've decided to keep it as a supplement to my workout program. For most people, though, I would think you would prefer doing 5 minutes of ab exercises a few times a week for the same or better results. Worth a try, though, to see for yourself.

I started using proactiv when I was around 22. I had never had acne problems as a teen, but all of a sudden around 21, I would get these large painful cystic blemishes maybe once or twice a month on my chin. They tore down my self esteem whenever I had one. I would be afraid to leave the house and try and schedule my life around the stupid things. These were not little baby white heads, They would take a week or more to come to a head and hurt like you would not believe during that process. Then, they'd take forever to heal. I'm fair with freckles, so a honkin' red mountain the size of a nickel or dime was not good.

An awful lot of detail in this biography which was a bit offputting, but overall it gave a good picture of Lucy and Desi. I learned many things I never knew before.
