Compact tool. The light is perfect for working in tight spaces and working with the power off to do electrical work. The check power function is fantastic; I don't need to have another tool with me.
Works well for working on 110 v switches and plugs. It detects live voltage in the circuit which can assure me (as the user) the circuit connections are not electrified.
I've used this screwdriver a few times. I am pleased with it. It could be dramatically improved if you could lock it, preventing blade rotation so it could be used as a manual screwdriver.
