Zareba Wood Post Screw-In Insulator, Black, Pack of 20 is rated 2.3 out of 5 by 19.
Rated 1 out of 5 by from Piece of garbage. In short, these are the worst insulators EVER, and should no longer be in production. A third of these snapped in my hand as I was sinking them into the posts. I was not using anything to apply leverage to them, either, just my hand. Of the ones that did not break upon installation, more than half had broken in the 3 months they've been on the posts. I do not have high tension wire, just temp. electric fence that should put little to no strain on these insulators. If you plan on using these...DON'T!

Rated 5 out of 5 by from Easy to use, simple to install - it works! I've used these in my sheep pasture and they have worked very well.

Rated 4 out of 5 by from Cheap and easy insulators You get what you pay for applies to these. If you want permanent insulators buy more expensive ceramic ones. You should pre-drill for both kinds. These will work okay for lite gauge wire (17 ga.) but can't hold up to the tension that heavy gauge wire fences need. Not good for corner post where you will be pulling against them, even on 17 gauge fence. They will break quicker with tension on them, either from fence tightening or from animals pushing on fence. I have broken several off when installing them by using pliers (with pre drilled holes). They are strong plastic, but don't expect the performance of ceramic at this cheap of a price... I have learned to only use these on the line post to hold the wire in place and I use other means at the corner post or at any tension point (mostly ceramic insulators). Only been using them for a bit over a year so I can't say how long they will hold up to the hot sun and UV's. Time will tell, but as cheap and easy as they are I will simply replace any as needed. I only have a hot wire fence for a few goats and a digging out dog. Started out with a small zapper and it cured the dog but the goats would still break out. Once I got a larger zapper ( .5 joules ) that cured the goats from going anywhere near the fence, even my large male wanting to get to a separated female in heat. Bottom line, If you need a permanently secure hot wire fence (for large headstrong animals, or crazy deer...), don't rely on them if you don't want any consequences due to one or more of them breaking, possibly causing your electric fence to be inoperable. If you need a semi permanent fence, they are cheap and easy.

Rated 4 out of 5 by from Nice for temporary fencing By temporary, I mean a few years, lol. We used small electric string fencing with step in posts and wooden corner posts. Used the screws on tge wooden posts. Don't recall any breaking. I know I did have one break this year when horse broke through the fence in a huge storm, but fence broke as well. We always drilled pilot holes on most things we screw, so maybe people need to try that. If you're foals are hard on fencing why do you have them in anything but wood or hot cote? I liked the screws, they worked great with correct installation ;)
