    1. handy Review by V'apa

      works as intended, i use it all the time. great little tool (Posted on 7/18/2017)

    2. Seems to work Review by Mark

      Well, what can i say. I haven't tested this unit against anything that i can know for sure in regards to calibration but it gives the results i expected when i use it. Cheaper units can be purchased from other sellers but i like the knowledge that J&L will stand behind anything they sell and i decided the extra 5 dollars was well worth that peace of mind to me.
