First one I received broke within hours after I got it.  Took a chance and got a second.  So far so good.  Its quiet and no annoying lights.  I have had this one for about 3 months.  If it screws up, I'll let you know.  As long as this hangs in there; I wouldn't be afraid to get another one of these if I get a couple more automatics, but there is another one for 6 bucks less so I might give that one a shot.  Anyway Amazon is terrific as far as returning things.  I gave this one 3 stars because the first one went south; if the second one was the first one, I would give it 5 stars.
