Fairly easy to install, just had to dig out some rocks. Works like a charm!
Immediately stopped digging in hole! No escape yet
Worked well. I wish it was a little narrower so the fit wouldn't be quite as loose, but it is a great tool.
Keeps our Great Pyrenees on our property!
Installed dig defence around our backyard. It did the trick, prevents my little friends from trying to dig under the fence and rumble with the neighbors dogs!!
