After reading some reviews about broken coating issues, I was a bit nervous to buy this. But, I needed a heavy duty, high insulation option to put in a new underground fence. I tested it on the spool before putting it in the ground, and instantly my system worked, so we knew we were good to go.We learned after using 20 guage wire that came with our system 8 years ago, and fixing breaks over and over, that we weren't going cheap again. It was thin, and broke so easily (not this brand's wire).We used a dog wire trencher, and this went in beautifully! It took us 2hrs to do 4 acres. I will say though that instead of putting the 2,000ft spool on the trencher, one of us walked ahead and put the spool on a rod, laying out the wire beside the trencher. This eliminated any kinks from happening and also insured that we weren't pulling on the wire we just put in. 2,000ft was quite a hefty amount.We have plenty left, and I hope we don't have to worry about it for many years to come. Very impressed, and would highly recommend
