I bought 3 different products, and none of the chargers are cross compatible. I will not be buying this brand again as I have a lost charger And so I have a completely useless product and the app sucks.

I liked the idea of a collar with vibration and sound versus shock or static. Didn't want to hurt my dog, just wanted to get his attention. The vibration works the best on mine, he learned within a day or two that when I called his name, I wanted him to come to me. In fact, it worked so well that I no longer need the collar for the negative behavior he displayed when I first bought it. And that's a darned good thing because an updated to the app in late April this year (changed from one app to another, forced not by choice) has rendered the collar worthless. The app itself is impossible to connect to the collar 99% of the time. If I was buying a collar again, I'd buy the same collar but would NOT opt for the phone app. I'd get it with a remote. The collar works, you won't hurt your pup, (don't use the static!) and the end result is the exclusion of negative behavior. Just be sure you don't get the one with the phone app.

We purchased this a few years ago for our male dog but have since started using it with our younger female. Unfortunately the range is terrible. It says 75 yards but honestly only goes about 50-75 FEET. This is unfortunate because it doesn’t work where we need it to. I’m disappointed because now we will have to spend extra to buy the remote version to do what we need it to.

The range is very small, a lot shorter than advertised. Battery dies very quickly so I constantly find the collar not connected.
