Review on FREWIK Waterproof Rechargeable Electronic Vibration by Rachel Yates

This is a good collar that is easy to adjust and fits any dog. It has two lengths of electrodes that you can swap out depending on your pet's coat length. The included USB charger has two ends, so you can charge the remote control and the collar at the same time. I made a mistake trying to read the instructions. It would be better if I just started pushing buttons and sorting things out. Just charge and go. It's easy to use. The most difficult thing is to correctly attach the electrode box to the collar and adjust it to the correct length for your dog. This is easy enough for everyone to understand. Unlike the last training collar I had, it includes a handy tester. I made the mistake of "testing" the last one I have on hand, so I highly recommend using the included tester instead.
