    • Great product
I wonder if they will last (plastic), but used them to tighten galvanized wire berry trellises. They are easy to use and convenient to tighten as the wires sag. So far I'm very happy with them.

    • The work well
Used on electric fence. They must be installed when running new fence wires. Installed they work very well and keep the wires/line tight. Easy to install and use.

    • Works well with poly wire
Worked well for the poly wire fence I put up around my garden. I am glad I used these as the wire seems to slightly stretch over time. Just remember to put them on while putting up the fence, hard to add after.

    • Simple and Works Well
This electric fence tightener does exactly what it’s supposed to. It’s simple to use, sturdy, and makes tightening the fence quick and easy. Nothing fancy, but it gets the job done.

    • My go-to
If I need to string up lines of poly rope or poly wire and get some good tension on it, these work very well in stead of using a metal ratchet strainer. Quick and easy way to get tension on either permanent poly rope fence or temporary sub-divides using poly wire. Well worth the price!

    • Plastic
Tightens but gears are plastic and slips with tension
