Great device. Well made.
This item is great. Very well made and works great. Can’t test connections anymore without it. Very convenient and impress on how it automatically switches between voltage to continuity

great features and much better than old tester
I love this new tester; much more convenient and feature full over my old light bulb 12v tester. I am debugging an electrical issue in a mobile home and I am leaving it in the engine compartment (connected to solid ground) for quick voltage and continuity checks.
