Portable Ketone Meter Provides Digital Readings for People's Ketosis Content in Breath

Does not work! Save your money... find a better meter! It would tell me along with my coworkers and my daughter who consume tons of carbs and sugar that we were all in ketoacidosis or would just show a E.00 signal after having it for three days . Returning today

Very easy to use but it stopped working and only gives me an er4 code. I have no idea what that means since there are no trouble shooting instructions.

I tried multiple times on different days and received nothing but error messages. E3 and E2 to be specific but there’s no way of knowing what they mean.

Fail to operate after 2 weeks!

The battery compartment is huge and the springs that hold the batteries in are flimsy, so the batteries keep on losing contact just by turning or moving the device. It also seems to be constantly draining the batteries whether it's on or off. It burned through brand new batteries in less than a week.The accuracy is questionable. Depending on how hard you breathe, or when you inhale, readings vary widely.

I get a green light (valid reading) and it gives me 9.95 out of 10. meaning I would be in a state of KetoAcidosis and need medical care... Wasted money...
