I think there are probably varying opinions on this, and perhaps others will chime in. You’ve probably heard already about the variability in accuracy with home measurement of glucose, but I’m not sure there’s been a consistent reason to think one brand is more accurate than another. I personally use a Precision Neo and have been pleased with it, but that’s based on nothing other than the fact that it always spits out a number at me.
Except, actually, I have definitely noticed that the physical ways I can tell my body is undergoing a period of greater ketosis (taste in my mouth, etc) and similarly when in periods of greater insulin resistance (usually for a couple of weeks prior to each period with some bloating and increased hunger, etc.) the meter results have correlated with what I guessed I would see.
Addendum: a lot of people on the forum like the Keto Mojo, but I don’t know if it measures glucose. There’s nothing wrong with buying a separate meter for each, of course. It would, if nothing else, save you from having to change out the strip while trying not to inadvertently wipe the drop of blood off your finger. I’ve gotten good at it now, but it took a little practice at first! If you get the Neo, I’ll tell you the glucose strip gives you a reading much faster than the ketone strip does, so I always do the glucose reading first.
