2nd one we've had. This is a..maz....ing! The power from this little Beast is fantastic; my wife is a Yoga Teacher of some renown and uses it in her various classes of 20+ students. The reason it didn't get 5 * is because the previous one only lasted 15 months,but so inexpensive.We phoned the Azatom Company who said they probably could have repaired the malfunction, but it would be easier to purchase a new one (only 12 mth warranty). Still...this is so good hence bought another one.
