    • "72-7730A" by dzignr on 9/8/2014
      Overall: 3 out of 5

      Just received via postal service today. I am impressed with the overall quality of the unit. The pricing MCM was offering the meter at was valuable. I am working through the manual and so far all is well. Backlight is nice. The case is great as well; it has elastic cords to hold everything snug within it. Sleep mode works well. I won't pretend to be an expert with meters, however I believe this Tenma will assist me along my journey. MCM gets a great thanks too.
