I use mine all the time. Hardly every pull out the multimeter or test leads anymore. With one touch you can check for power or ground, no flipping multimeter switches. It also can provide 12 volts as well as ground signals. Does it all except check resistance. Easy to test all relays, bulbs, switches, solenoids, etc right away without running test leads. Built in breaker so easy to check shorts as well. Only warning is it is very easy to put 12 volts to something you may not want to power up so don't get to crazy with the rocker switch and put 12 volts to everything trying to test something.
