Product Review

works well. It does take time to install and one must be careful to not cut the wires

"This gives a warning by sound and buzz. There are many levels of sensitivity

"I love that you can adjust the settings on this

"I recently adopted an 11 year old dog and I was told the previous owner used a bark collar on him. This dog DOES bark a lot--when left alone

I was skeptical at first. But this is the best underground DIY fence on the market. Easy to install and have had it for 3 years bod-eeee with no problems. Even bought my son one for his bully pit. Works great. Haven't had one issue with it.
