3M Hand Wire Connector Driver WCD-H

I bought this for my fiancé as a stocking stuffer for Christmas. He loves it. His friend loves it. It saves their fingers from manually twisting on a wire nut which eventually will cause hard calluses on them. I will be buying another one for his friend soon.

Saves the wrist when you're making up lots of boxes. It does take a few uses to get the technique right.My only complaint is that it squeaks like crazy when you use it.

This tool performs exactly as they say it does. I won't say I use it all the time, but as an electrician, wire nuts tend to happen to me. The only problem, that is on the manufacturer, as they come to you a bit dry. And what I mean is, the first time that you use it there will be an annoying squeak. Drop a little oil, or grease, and your problem is solved. I will caution those who buy this though as to how to use it. It is very efficient, so efficient in fact that you might want to check your wire nuts so that way you don't have any bumps or protrusions from the top.

Handy device and definitely speeds things up when making joints. Get it. It is worth every penny and the space it takes up in your pouch.

Bottom line, it does not work. I do electrical work quite a bit, and thought this would save some of the finger/hand fatigue, and possibly save a few minutes throughout the day. I have tried several different wire nuts, both winged and regular. The winged ones work sometimes. But not often enough to justify a specialized tool. I'm back to twisting with my fingers. I would not recommend this item to anyone. Very frustrating trying to save time only to waste more time than usual trying to use a tool that rarely works. The only way I could see this working is if you only use large winged nuts (larger than 10 awg). Even then, it just doesn't grab all of the time.
