Solar “must have” tools.
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
Great for old hands. I have weak hands and these help me undo my solar when packing up camp.

Good product, buy many
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.

About average.
Pretty good, when they work. I have a few MC4 connectors where I have to crab press these a little more to unlock the MC4 connection. Wish they worked on all, but I guess that might be wishful thinking. So just okay value for money, fit, and ease of use.

Good for MC4 internal connector binding
There are some MC4 solar panel connector wires that use an internal connection binding. This type of tool makes this kind of MC4 connectors easy to disassemble. Without this style of tool, it’s a struggle to get the MC4 connectors apart. The other type of MC4 connector uses external binding which this tool will not separate.

Wrong size and breaks in a week
Made from super cheap pot metal that broke within a week . Also did not fit my mc4 connectors for removal. Avoid.

They do the trick!
I recently added a solar panel to my camper van and while testing the cable connections did not realize that MC4 cables needed a tool to disconnect them... whoops! These arrived quickly and worked great. I have a couple in my van and a couple in the workshop, just in case I need to use them again. The blue color makes them easy to locate in my toolbox.
