I bought a few bags of these as the price was attractive and they included the nails. Installed pretty easily as long as you are good with a hammer and don't hit the little knob on the top that acts as the fastener. My problem is that I have to replace them at a rat of about 8 per month (800 feet of fence) as they all tend to snap at exactly the same place, the bottom just above the curve, and apparenly for no reason. I'd buy more if they didn't break but having to replace so many, they are actually more expensive in the long run. It's back to higher quality for me.
