My Dr recommended Keto Mojo over the breath based KetoScan lite I've been using. Far and away this is the most difficult blood meter I've ever used. Hard to open the individually wrapped strips. I went through three trying to get a successful blood and ketone reading and these are the most expensive test strips I've tried. It's about a dollar a test. A DOLLAR per test. I test my bs several times throughout a day. The keto scan lite costs about a nickel per test. The app is nice and the GKI calculation is cool. But frankly, this product will go in my desk drawer only to be pulled out when my Keto Scan reading is above 40 (which happened once, which is why my Doctor had me get the Keto-Mojo that he trusts more). The bs reading was 87 and my accuchek was 99. Close enough. The keto scan breath reading anbd the keto-mojo both indicated I wasn't currenlty in ketosis. This is only one reading to compare, but that one reading cost me $3 because of the multiple attempts to get the Keto-Mojo to "sip" up the blood drop.
