Negative Positive
Title: Garbage
Review: I don't know if I was sent a defective unit, or if my Labrador just chooses to ignore the sound. Sometimes he'll look at me when I push the button, as if he's wondering what I'm up to. As for having any effect on his behavior, absolutely not. I could do better with a squirt bottle. I would send it back but I'm not going to bother with the shipping costs (and the ones I've already lost in the original shipment). I tried to save ten bucks with this item and I got what I paid for.
Is the review positive or negative?
