I had bought this product when it was first launched , I waited for it and keep cheacking my amazone account .And a day came I finaly got a chance to buy one .When it first came to my door step I could not believe my eye that I got a chance to own one .but after some day of use that it is only a crap as in is to inaccurate and also the band with it is not so good look on hand .then I graduly realise that it is a coaded vibrater thich can do any thing .i sugest peope to simply write the use of this product in their daily life and then buy it.
