I like the reduced cost of keto sticks, and you sell based on superior accuracy so I assume more accurate than Precision Xtra (I have both). And the required blood volume is smaller. But things I dislike: 1. Testing side by side I get very different numbers the PX and KM meters. Which is right? I have no way to tell. 2. I went into significant ketosis during a recent fast, and PX showed my ketones at 6-7, but the KM just said ""Hi"". That's pretty useless - need the working range extended. Fortunately I was using the PX meter in parallel or would have had no way to calculate GKI. 3. Meter is larger (minor complaint) 4. The lancing device was unusable, I had to throw it away. I really wanted to like this meter but was disappointed
