Rated 4.9 out of 5 by 11 reviewers.
Rated 5.0 out of 5.0 by Very well thought out meter This meter will automatically sence A/C and D/C voltages and respond accordingly, this is a very convienient feature when working on power supplys and any equipment that has a mix of the two throughout the unit. It is very compact but tough and will fit in tight spaces. The test leads are high quality and have a comfortable semi soft grip that helps them stay where you want them to. The lighted display is easy to read and as accurite. December 6, 2013
Rated 5.0 out of 5.0 by KLEIN TOOLS MAKES EXCELLENT PRODUCTS Klein Tools makes excellent products and this multimeter is no exception. The auto ranging function of the MM500 multimeter saves time by allowing you to test AC voltages or DC voltages without having to set meter to type of voltage. The meter even has a function to save a reading so you can go back to it if need be. The MM500 is very rugged and seems to be able to stand up to years of use. December 6, 2013
Rated 4.0 out of 5.0 by Works as Advertised Don't have much experience with this tool but soooooo easy to use. Smart design all way around. Seems more durable than most. December 27, 2014
Rated 5.0 out of 5.0 by Easy to Use and Tough I like the fact that it's easy to use, but I like the fact that it's tough even more. I've dropped other meters and broken them, but this meter stands up to my lack of coordination! October 2, 2013
Rated 5.0 out of 5.0 by I am not an electrician, but as a homeowner this device is very easy to operate compared to any other device I have found. I am not an electrician so I am not sure how professionals view this product, but as a home owner this device works great. Set it and forget it. It's not hard to test whatever it is your working on, from Christmas lights to irrigation this device works great. I would recommend purchasing this unit to anyone - electricians may have better units available but for the average consumer this is the one to buy. February 18, 2014
