Great

Works great. Good quality coating on the wire. Cost more than others but it's worth it. I have another set purchased for a different seller and the coating cracked off the first time I used it.

I've never actually used wiggle wire before, although I knew of its existence. I'm in the process of building a chicken run (from EMT) and wanted to put a 55% translucency greenhouse plastic on it to keep most of the weather out. After struggling to make greenhouse pipe clamps work (through hardware cloth) to get the sheet plastic tight, I threw up my hands and ordered this. What a difference! First off, the self drilling screws actually work (granted, it's aluminum, but still . . . ,) and installing the wiggle wire in the channels couldn't be easier. I found it very intuitive. Also, changing out the plastic sheeting down the line when it inevitably fails (although this stuff is supposed to be good for 4 years minimum) should be a snap. I'm sold. Now maybe I'll need to build an actual greenhouse.

Sad but true, we had a tornado come through and rip our complex apart. Our greenhouse became a kite and was relocated a mile away. HOWEVER……. These rails never let go, everyone of them was still holding onto the plastic and at spots the plastic ripped before these puppies let go, very impressed and when we become less discouraged we will buy them again….

Just purchased more to expand our project. We have been using this for 3 years now on our chicken run in the winter. Holds the plastic tight. Tracks are holding up great. Easy to get the wire in and out of the track, but very sturdy when in position. Winters are brutal in KS and these make the run nice like a green house. For us, it was definitely worth it.
