I love my Keto-Mojo meter. It is very easy to use and read! What I do find questionable, however, is the accuracy of the blood glucose readings. I have a professional medical-grade glucose monitor that is usually as accurate as the one used in my Drs. Office. The glucose readings from my Keto-Mojo consistently read around 20 pts higher than other monitors. Since the other two monitors are similar, I consider the Keto-Mojo the outlier, and perhaps not as trustworthy. But overall, I do like the monitor and feel it does a good job of measuring ketones so I can be sure I am in Ketosis.
