I use a cheap breath tester to see if I'm in ketosis when losing weight (burning fat creates ketones, which trigger breath tests).

Jus' sayin'.

You should be skeptical of the output of a ketone measurement device. You need to measure blood concentration of beta-hydroxybutyrate to accurately determine your ketosis situation.

What's the precision of that device?

How does that compare to using test strips?
