Lasts forever and we love the ability not not just shock but also buzz and vibrate. Haven’t changed in a month because the battery is so great!

Works likes a charm!! Thank you! My dogs behavior has dramatically increased my with the aid of the little collar!!

My pup reacted exactly how you would expect her to! The bad behavior is already starting to let up!

I love this product, thanks to the range and long battery life my dog has become the best behaved partner I could have asked for.

This worked really well to stop a barking problem. I’ve had it for a couple of months and have never had to recharge. It is really easy to use. No complaints!

Great training tool
