Review title: Either it works or I've lost my hearing
Product review: I bought this a few weeks ago from Petco for $60. I was skeptical because the reviews weren't so great. I just rescued a 6 month old pitbull/bull terrier mix and while she never usually barks, she hates going into her crate. I bought this for when I'm not home or when it's time for her to go to bed (she sleeps in her crate). She used to bark for 30 mins and now I barely even get a whimper. Either this thing works or I have lost my hearing! I am returning the one I bought at Petco and am buying this one since it saves me $30. Best investment I've ever made. You need to try it!
