Ideal Electrical Twister Proflex Mini (30-643J) Orange/Blue Wire Connector, Jar of 500 — Compact Twist-On Wire Nuts for 22 to 12 AWG with Comfort SureGrip and Flexible Skirt

Use these daily in my electrical business. They work great.

As an electrician of 6 years, these wire nuts are simply the best. They bite easily, hold great and most importantly feel excellent on your fingers.

These wire nuts are Awesome! They have a little skirt around them that kind of hugs the wires once installed. They go on easy, grip good and are smaller then other wire nuts so fit in the box better.

These are much better than the standard wire nuts, and they will prevent problems from shorting woth that skirt added to the bottom.

Although the product description doesn’t indicate it (only the picture), this connector allows one to securely connect a mix of both solid and stranded wires. Many connectors do not provide this capability and often the stranded wire will not securely “mate” with a solid wire.

I like them for tight spaces such as multi gang receptacle boxes since these have a lower profile. These are not the strongest wire nuts, however, if you do a lot of strong turns the solid wire can poke through the plastic tip. But it's great for saving space.
