## Customer Reviews

### ⭐⭐⭐⭐⭐ Solar “must have” tools.
*by T***S on July 11, 2025*

Good function for the budget conscious people who want a decent price on a product that works. Item function is good, though. My fingers are too big for the solar connector release mechanism, so I use this particular tool constantly.

### ⭐⭐⭐⭐⭐ Great gadget
*by S***L on April 26, 2026*

Great for old hands. I have weak hands and these help me undo my solar when packing up camp.

### ⭐⭐⭐⭐ Good product, buy many
*by S***R on July 29, 2025*

These work very well but you need to buy 2 packages. They are plastic, which will break but seem to work the best of the MC4 spanner tools. Will buy again.
