This collar is a great valve. Works perfectly. Comes with extra rubber covers. My only complaint is that the strap needs to be more user friendly for small dogs.

Best bark collar

Best bark collar we have owned. Easy to use and program. Works great

My dog loves this collar (no he doesn't, but I do!). Small, and easy to wear and appears not to be too bulky like the last one I had. I love that it is rechargeable, but has a pretty long shelf life. Definitely works.

My dog always like to bark every little thing ,and my neighbors complain it a lot. So I bought this collar to try. The sound and vibration work great and only use several time my dog barely to bark. No more comments form my neighbors. Recommend it !

This is really a God sent gift. Our minipin barks incessantly. It is so bad that our neighbors called the pound on us. We live in the country on 2 acres. Granted, that says a whole lot more about them as both of neighbors have dogs who bark for everything also. But we don't want to have a record with the pound. That's scary that we could lose our dogs for petty things, such as too many complaints. Now, our dog is quiet for a few days before we need to equip the collar again. Its especially nice at night when I'm trying to keep the home quiet for the baby. Thank you for the peace in quiet. It really works guys. I'll share some pictures later on but I've been using this for a while now, and it still holds a great charge and it even works for our rowdier mini shibahusky. Now we just need to find an effective way to keep them in the yard so they arent stealing from the neighbors. ...good grief! LoL ...
