Great value, basic and inexpensive but works!
This is about as simple as a thermal wire stripper can possibly be. No moving parts, no power switch. It does a good job with little learning curve. So far, I have stripped about 1500 wires in a production environment where we previously used mechanical strippers. The difference is night and day. Much faster and FAR less fatigue. Starts to lose effectiveness when the wires are smaller than 26ga. I have done 18, 20, and 22ga mainly.
