3M(TM) Performance Plus(TM) Wire Connector R/Y+JUG, 500/jug, Replaces 2 standard connectors, For all types of jobs

These are pretty good marrettes. I've used them up to 8-10awg with success, more often I'm doing 12 and 14 which these are perfect for. They bite very well, and if you have to take them off they still come off without buggering the copper or shearing it off inside the marrette. I'll be using these for the foreseeable future.

These are great and a good value.

These things are great

This is my first time using these. They seem to work well. Even though they cost a little more, I like that it covers 2 different sizes of wire nuts. It takes some of the guesswork out. For the project I'm working on right now these should work everywhere a wire nut is needed (except ground. I'm using greenies for those in some tight places). It will probably take me a while to use all of them, so it may save me money in the long run vs. having to buy and keep track of 2 different sizes.

Conectores muy confiables para el empalme de los cables eléctricos, y nunca me han fallado.
