The Zaaz All Body Movement Vibration

Costo sells the Zaaz all body movement vibration machine on their road shows in some of their locations. I have heard of people losing weight with the machine. One lady told the customer service representative that 2 lost 2 dress sizes and she wasn't even trying to lose weight. lol She got rid of her arthritic knee pain for which she used to have to take 2 meds for daily and now no more meds needed
