## Customer Reviews

### ⭐⭐⭐⭐⭐ Multimeter lead connectors.
*by A***R on July 25, 2025*

I use these to connect multimeter leads together as jumpers that don't have my fingers as close to the work. Fit like a glove for that.

### ⭐⭐⭐⭐⭐ Perfect for Simpson 260!
*by H***S on August 5, 2023*

We use Simpson 260 VOM for specific tests in electronics leaning lab. Some of our experiments require multiple meters and digital meters do not indicate some of the visual results we are expecting. That's where these lead adapters come in handy, we can use many of the other styles and types of leads we have on hand without having to buy $impson branded leads. If you have to measure higher voltages, I would not recommend any sort of adapter from a safety's sake but in a learning, lab using DC power supplies these are perfect.

### ⭐⭐⭐⭐⭐ Works
