The device is well packaged, feels good in your hand with a nice heft, but it keeps turning off. The booklet that comes with says that may be because you aren't using enough moisturizer, but no matter how much I use, it keeps cutting off. I haven't had it long enough to realize any results yet, especially with only being able to treat very limited areas with the "run" time I get out of the unit. I don't know if I have a faulty one, or if this is normal, but it is very frustrating.
