Customer Reviews for Klein Tools Digital Multimeter Electrical Tester Set

Does what it needs to do.

Exactly what I needed for my home repairs. An excellent value.

After having mis-wired a GFCI outlet, I decided this was a must. Easy to use, does what it says it does.

I’m pretty happy with them, (I bought two), with one exception, and that is there is nothing to help I’ll the testers out of todays tamper proof plugs. The side grip rails are slippery and don’t aid your fingers while trying to get them out of the plugs. Maybe include some rubber inserts or silicone inserts to help grip the sides or make the ridges less rounded.

IT IS S GREAT TOOL TO CHECK TO VERIFY THAT YOUR OUTLETS ARE WIRED CORRECTLY. IT IS VERY EASY TO READ AND UNDERTAND.

Great value and all items are very good quality

It helped me identify some previous wiring issues.

I liked the description of possible errors on front of tool. Clear and consise. Another brand printed codes that were un-readable.

This Klein tester is amazing. My home has seven GFCIs, and it has been a challenge to track which devices protect which outlets inside and outside the house. This tester tells you of outlet mis-wiring, and will trip the GFCI allowing you to map the protection zones. I which I had one five years ago!

Works well and is easy to use. Plug and play...if outlet works. If not more plugging and playing but not testers fault.

I have used the Outlet Tester to ensure the power is off as change out my electrical outlets. It is easy to input into the holes and based well. I especially like the guide on the item that indicates if there is a problem with the wiring. The added feature is the GFI tester which allows me to also test the GFI coonection with a touch of the button.

Worked great! Just as I expected. Super easy. Found out there was no issue with outlet.

High quality, compact, and very easy to use. Totally met my expectations. Another great device from Klein Tools.

Very useful tool. Works for regular and GFCI circuit testing.
