This product does not work at all!!!! Don't waste your money!!! Unfortunately all I can do is throw it away bc I missed the return window by two days!!! But we had a lot of rainy days and the dogs weren't outside as much. It is even under a covering where wind and rain can't get to it, but out in the open near the dogs level. It it hanging under the canopy of a wood swing. I tried it a all levels. Not worth it!!!!

I had low expectations for this product but I am blown away. Our neighbor's dog would go out several times every day and bark non stop for hours. So many Sunday mornings woken up with the barking right near our bedroom window. It was getting out of control more and more each day. Any time I would go outside it would start barking again. This was a desperate shot to see if we could at least reduce the barking. I mounted it to our fence and said a prayer and to my disbelief the barking has stopped completely since DAY 1! Sometimes I hear her on the other side of their yard in the distance...and a few times trying to bark at a very low volume. This thing is worth its weight in gold! I don't know what else to say but try it yourself. Your sanity is worth $20. I am sure our neighbors are also less stressed out. I know they were frustrated telling her to be quiet. It has been through quite a few heavy rainfalls too. I made a little roof out of wood for it just to reduce the weather on it.

Seems like a quality product, glad it works for some people but it had no effect on my 15lb PomChi. The only thing that works on him is the static bark collar, but I wanted to try this. The vibrating collar worked for a few months, but not anymore. I tried this on the different settings and watched him on the doggy cam. Nothing changed.

Well, there are all sorts of warnings on this device about damaging human hearing as well as dogs hearing if too close in proximity. I wanted to use this indoors near a barking area where dogs stay by a window, but immediately turned it off when my own ears got sore. I covered the speaker a bit prior to use (based on the warnings), so it is good to know that ahead of time. I placed it outside now (also a problem area for my own dogs) and haven't had a chance after a few weeks to use it (when I've gone outside to turn it on my dogs just happened to come in). Waiting to see if it is effective (they are not well trained, so I'm guessing it may work for me yet). Two mounting screws are both on the top of the unit (one on top, one on bottom would be a better design) and the battery is on the back, so plan on pulling screws whenever you need to change the battery, I probably should have used a "heavy duty" battery for lower power / longer life... but didn't for now. The switch seems to work easily.

The product works the only gets the attention if the dogs are medium or larger and if the dog is aggressive doesn't do anything but stop them because it is an unusual sound they're not used to but after trying every level they become accustomed and it didn't even matter that it was on and the battery life non-existent I use the best batteries a high-end Energizer lithium and within 2 days the battery was out it's just too expensive to keep replacing batteries like that but I will say for the smaller dogs in the area it worked like a charm

This product does not work. I set it up unobstructed, one foot off of the ground and 3 feet from the face of my neighbors barking Chihuahua, Pomeranian, and Golden Retriever. IT HAD NO EFFECT. I am just sorry I waited so long to use it as now I can no longer return it. A waste of $20.

Works, but battery only lasts days.

This battery life is atrocious. I have to change battery around about every 2 weeks. While I believe it works when it’s in use, I would simply avoid this product at all cost given the amount of batteries you have to use - that cost adds up quickly!!!! 1 star just because of that.
