Review on Ultimate Dog Training Combo: KoolKani Remote Shock Collar & Underground Dog Containment Fence System by Kara Smith

The product worked perfectly until the remote control stopped working last night. The "A" key became completely unresponsive, and the other keys on the left also became unresponsive. I have tried reconnecting the collar and charging the remote control. Nothing helped. I read all the other reviews and bought all sorts of replacement parts just in case and didn't have to use any of them. However, I could not use the underground fence because the ground was frozen. However, the convenience of one remote control for three dogs at once was remarkable. It was very easy to switch between dogs and change settings. I'm very disappointed that it didn't work.
