The old version of the monitor was awesome. I absolutely loved it. When I tried to reorder strips I was prompted to upgrade my meter, as the old one would eventually no longer be supported. The new meter is in my experience extremely unreliable and inaccurate. I reached out to the support team, and a specialist told me the new meter was far more sensitive than the old one and gave me some best practices to get accurate readings which included hand washing instead of using alcohol wipes, discarding the first drop of blood, and not pressing near the puncture. I gave it a solid week of testing. I’m fasting for 16 hours a day and eating only ten grams of carbs per day from leafy greens, absolutely no sugar, and hitting my protein and fat macros exactly. I just find it hard to believe that after three months of eating that way that my blood ketone level could be 0.4. I am extremely disappointed and asked for a refund for the meter as I’m starting get develop an anxiety complex about this. I’m just going to keep eating clean, and use weight loss or clothing as a metric. I would save your money.
