I installed this in June. Its now November and it had not failed once. The batteries last longer than stated, probably because my dog doesn't test it often. I installed it myself with an edge. The controller is in my garage and the wire meanders around about a half acre of gardens and pond. The training manual was super super helpful!!! My dog knows exactly where to go and not go.

I am glad I invested in this training collars.

Vibration is set for 2 I use it every day. Battery was charged one time two weeks ago , still 2/3 charged.

I highly recommend this training collar!!

The dog training collar is very easy to use and charge, and has excellent battery life. We are very happy with our purchase!

Highly recommend. Installation took approx. 3 hours with two people. Rented a wire and cable burying trencher from local hardware store. Trencher did not bury the wire well, so we did some manually work on hands/knees to bury into ground. Wired through a crack in our drive way to completely surround property. We surrounded our 1/2 acre lot, but ran out of wire near the end and needed to buy additional wheel of wire. Took some trial and error with collar settings to find the right amount for our 30 lb dog. After 2-3 weeks of training, our dog knows his boundaries. Still continue to have him wear the collar though....
