[Build-It-Break-it]

I have it and use it at home all the time. It's nice to be able to put power or ground to anything you need right at your fingertips. Test blower motors, power seats, fuses, battery voltage, etc. I had the power probe 2 stolen awhile back and bought the 3. I'd buy it again If needed.

I think tool topia has them for around $69 or $89 bucks when they're on sale but I never really compared the prices. I know Matco and snap on charges $145 on the truck for them tho.
