These were much better grips than I expected for the money. Clamps provide a strong connection with good continuity. I use them when discharging CRT monitors where I could potentially be exposed to hundreds and even thousands of volts of current and I have every reason to believe that they give me a full anode to ground connection even with the screwdriver move everywhere, everywhere, everywhere. I check for continuity throughout the process and that's always a good thing. I also like to have different colors on hand.
