Review title: I bought 3 of these, THE DON'T STOP BARKING
Product review: FIRST, DO NOT BUY THIS DEVICE! I have purchased 3 of these devices at once. I SURROUNDED the dogs (in their area) with these devices and they simply ignore them and continue barking. I have a feeling the the auto-detect feature works sporadically, at best. The manual button works, but it still does not stop the barking. The dogs will most likely notice the sound at first, ignore it, and continue barking. Also, you will spend a lot of money on batteries, as they seem to wear out quickly. ONE of these devices SHOULD work for barking dogs, and I bought THREE at once, and the barking continues. Please, save your money for something else (Ex: A Citronella Collar).
