2 in 1 Dog Training Collar Automatic Anti Bark Control with Remote Rechargeable and Waterproof for 3 dogs

I like the options on the collars and the different levels of sensitivity. The collar also comes with a one warranty which I find nice. The company appears to stand behind their product. I found most other companies do not offer this. I bought two of these collars for my two small dogs because of their unnecessary barking. The collars did their job and now the neighbors are happy.
