Highly recommended fence product
This is an excellent product, and easy to install. We ordered a 4x4 mesh, 6-ft high fence, 300 linear feet. I've almost finished installing it - it took around 25-30 hours or so for one person. The 12.5 gauge wire they send out seems pretty sturdy, enough for my German Shepherd.
Some suggestions: if you have rocky ground, you should purchase a drill-mounted auger and use that to drill pilot holes slightly thinner than the stakes otherwise you'll have a really hard time. I wouldn't use the hog ringer as it's fiddly and doesn't draw the two wires close together. Better to use zip ties (so you'll have to purchase more zip than they send out). Make absolutely sure your stakes are level because any errors here will be magnified with a 5 or 6 foot post. Overall, it's been great to install. We saved thousands of dollars by DIYing it!
