### ⭐⭐⭐⭐⭐ Works as expected and give you the voltage as well
*by O***E on June 15, 2026*

Works as expected, comes with a tip cover for storage and safety, it is a good price for the tester. It is very easy to use as it only plug to ground and the tip can go to any wire you want to try. I used it to test charging voltage and also to see what fuse output had the current and if it was working as accessories or with the on switch. The size is a regular screwdriver
