Sonic Anti Barking Deterrents Control Device, Ultrasonic Dog Bark Deterrent, Mini Sonic Repellent 50 FT Range, Ultrasound Silencer No Bark Training Control Device Security for Dogs

The neighbor's dog is no quieter but no longer spends long periods serenading me 8 feet from my bedroom window. She now moves away from that area within a few seconds. Not a perfect solution but a great relief.(It's not her fault, she's just bored & lonely and giant, with a bark to match her size)

not worth the money, doesnt do a thing to deter the neighbors dog from barking.

TL:DR Doesn't work with fresh batteries or on any settings.I placed it by the back door, where our dog goes to survey the neighborhood and bark. I set this device to low and waited. Dog still barking. Neighbor dogs are barking and none of them even slow down their barking. I guess it's back to the spray bottle for us. Don't waste your time and money. We even bought the Amazon batteries to go with it.

Our dogs barked at ANYthing, especially the delivery persons. This little device changed everything. It’s portable so we take it with us on road trips too. We were worried about staying anywhere due to their barking but this has opened up more opportunities

For starters, the device is very finicky and unless you see the lights blink, you don’t know it’s actually on. When it is on, it does nothing. My dogs were within 5 feet of the box when it was set to the max distance, and it did nothing to deter them from barking.I really wanted this to stop my neighbor’s dog from barking, but no luck. I’m returning this and looking for something else.

Does nothing to stop the barking. Even while my dog is standing directly beside it with it on high. Like...nothing, nada, zilch. Darn, It's a good price too and I hate to spend $40 but I may have too. I can't keep sending these cheap ones back and believe me, if they worked even part-time, I'd keep it. But it 100% of the time does-not-work. Sorry.

Annoying dog next door!

I didn’t like this product at all. It is supposed to help keep your dogs quiet, it didn’t even work at all.
