2pcs Wire Twisters Tool for Drill, Twisters for Wire Nut with 1/4" Chuck Wire Twisting Tool Electrical Wire Twister Wire Spinner Wire Driver Tools for Electricians Drill (Blue)

They feel really cheap but they get the job done

Would not do as advertised unless you use extra large wire nuts better off using you hand

Works as advertised. Not sure how durable it is due to being plastic. A metal model would probably last a lifetime.

This product not only saves time and some skin off my fingers, it does a great job of evenly twisting wire ends in order to attach wire nuts, solder, or other connectors.

These are too bulky to use if you're working residential.
