  • GREAT tester with Everything you need to test outlets.
Style: Receptacle Tester
I am an electrical engineer and do lots of wiring and wiring repair for myself, family, and friends. I have a complete set of electrical meters but this outlet tester saves lots of time and is very handy, easy to use, and can be used even by folks that don't understand electricity that well. I have other folks test the outlets and then they mark which ones don't pass and I fix them. This one is extremely rugged, easy to use, and fully functional. I don't have ANY complaints about this one and it has already been used to test and repair hundreds of outlets. You can't go wrong using this outlet tester. ... show more

  • Great device for finding electrical issues in your plugs.
Style: Receptacle Tester
My first impression was it looks great. After opening and using it, it performed better than I expected. It is small enough size to fit in your pockets. That makes it very portable, and it is very safe to use. The display lights up great and is easy too read.

  • Excellent Outlet Tester
Style: Receptacle Tester
The Klein Tools RT250 is an excellent little outlet tester. Especially how it retains and displays the information on the screen for several seconds after you unplug it, which is terrific when testing an outlet behind a piece of furniture where you don't need direct line of sight to read a tester while it's plugged in. ... show more

  • Almost perfect
Style: Receptacle Tester
This is a great little tester. I'd love to see this one have an "always on" feature like my fluke t+pro, so there'd be no need to turn it on. I'd like to see this with an audible feature as well. If Klein does that, I'll give it five stars. And just because of how big it is and how I like to carry it I kind of wish it came with a pocket clip. Still, it's my favorite little outlet tester. ... show more

  • Nice tool to verify your wiring is correct!
Style: Receptacle Tester
Simple little tool that gives me peace of mind that my wiring was done correctly. Plug it in and it goes green if it’s correct. It also tells you the amps coming through that outlet. I’m not an electrician but I don’t mind doing some simple wiring around the house and this lets me know if I did it correctly. ... show more
