Has anyone here used any of the invisible dog fences that don't use buried wires? Looks like there are two types that I can find, one that uses a circular pattern with a variable radius and another where you can program a zone for your dog to stay in - can be any shape you want. Mainly interested in the latter but would like to hear opinions of any of them.
What brand would you recommend? Stay away from?
Reliability?
Thanks.
