If you are ELECTRICALLY CHALLENGED, this meter is for you!

I needed a new replacement for my old harbor freight junky meter that for me was difficult for me to used. Simply put, I am completely ignorant on electrical matters. This meter does the work for you. Easy to read dial; just set it and go. Meter has good weight and the quality of the probes is excellent. I would buy it again.

Good Multimeter for the cost

Its a good meter but I accidently damaged my previous one.
Hopefully the autosense function will prevent me from doing the same thing again.

Perfect for home owners and D.I.Y.ers.

Good product. Large display with a back light, which comes in very handy. It has a kick stand and the build quality feels good. In addition, it has a small flashlight, No Contact Voltage probe, and you can snap the lead to the back of the unit for storage or for ease of use. Snap one probe on the back and hold the other. The dial is easy to understand. It's great for home owners and D.I.Y.ers. No complaints at all.

NOTE: No magnet or alligators clips if that matters to you.
