It really works!
This really works.  My hopes weren't up for this to function as described.  Blows me away how well it works.  I have bought more as gifts already and probably will again, unless I can get them to stop smoking.  Have purchased the smaller "mini" versions now, too, and work just as well.  I've not had long enough to know how long they will work but don't anticipate any disappointment.  Highly recommended.
