Didn't quite make it a year
At first I really liked this product.  Held a good, long charge and had multiple, strong vibration settings.  Then after around month 6, the little chrome button fell off.  Tried to glue it but it won't stay on.  Now, after about 10 months, the unit won't turn on right away and when it does, I can't turn it off.  It even turned on by itself in the middle of the night, falling on the floor of the bathroom and making a hell of a racket.  Scared the dog, who then scared us!  Also the +/- power button no longer works.  It actually does nothing now.  Its now in the trash.
