Review on High Tech Pet Deterrent Repellent by Holly Bell

Not working. Literally doesn't work. I bought it because my dog owners taught my dog to climb on the couch (they don't sit with the dog anymore, of course). It did not work. I bought new batteries to make sure it's not a bad battery. Still does not work. I sent it back but I didn't have a chance to exchange it (it was the same product but I don't know if it was the same seller). The dog still climbs on the couch when I'm gone, so I ordered a new one. This one doesn't work either. Tried 3 different batteries, all new (last one didn't work), asked my husband to try it to make sure it wasn't operator error. Still does not work. I now have a large supply of 9 volt batteries and a very expensive white dog bed. I won't buy any other.
