Waterproof Dog E-Collar Trainer with remote Rechargeable E-Collar for 2 Dogs

I love this collar! Bought for my Golden Retriever who kept running off every chance she had. I chose this collar for the distance that it can reach. It has worked very well for us. The only reason for only 4 stars is that I have had to sync the collar and handset a few times already and we have only had the collar for a month.
