Anyone use this? And if so do you have a heck of a time reading the lower end if the chart? I can't really tell the difference between 0.03 and 0.1 unless I put the vial half on the color and half on the white part of chart.
This may be a stupid question but does that effect the reading since the instructions say to place it on the white part looking down?
