Review title: Didn't work
Product review: Didn't work with my dogs...tried putting it in all different locations (on the floor, by the door, on a shelf)...always facing the dogs and never went off. The first one I got I sent back because I thought it was malfunctioning, so I was sent a second one...worked slightly better, but neither would go off when my dogs park. Needless to say, sent the second one back too and got a full refund. Loved ordering through amazon though, great exchange/return service!
