### ⭐⭐⭐⭐ easy to use kit.
*by R***L on October 22, 2015*

good case, easy to use. for my specific needs it is okay, could be better for my needs if range only went to 1.7 but the color scale remained the same. Reason being, the range I'm measuring with is in the .2 to .6 Still all in all it is a very good kit.
