      Great little DMM

      Overall: 5 out of 5

      Here in our physics labs we now have and use over thirty of these 72-7720 DMMs. We have compared accuracy against much more expensive DMMs and these units match up very well. We especially like the auto back-light on the display because we actually do several experiments with the overhead lights out as we need to be able to see an electron beam. Adjusting beam voltages is very easy when you can see the display on these DMMs in the dark.

      Great value for the money.

      Overall: 5 out of 5

      Although this is a manual ranging meter, it is user friendly and has many test ranges. It seems to be very accurate and it is easy to read. The automatic back-light is nice for dim areas. I use it for both A/C and D/C measurements.

      Good product

      Overall: 4 out of 5

      It is a very good product, the only thing I do not understand is the grayed out scales being hard to view.

      The price was right!

      Overall: 4 out of 5

      nice features, average accuracy, large clear display (but back-light somewhat poor) rugged construction, awesome value!

      great handheld

      Overall: 4.5 out of 5

      I have used this unit since 04, in pool automation electronics, musical instrument and electrical service and much to my surprise it has weathered, worn and operated, far exceeding my expectations of versatility. I need to replace it now but I have no complaints and changed the battery only once in its lifetime. A BANG for the buck. I was glad to see it was still available.
