Ketone Breath Analyzer Portable Rechargeable Ketosis Breath Tester Professional Grade Accuracy Digital Ketone Breath Meter for Ketogenic Diet Testing with 10 Mouthpieces

I was pleased with its performance for the first 6-7 months. After that it has only registered 0.0 or 0.3. There's an email address in the instructions card. I have emailed them 3 times asking if there was a way to reset it. They haven't replied.

This meter shows oom/L which is a BLOOD TEST unit to measure amount of ketones per LITER of blood that is NOT correct units for acetone in the breath ..Should be PPM PARTS PER MILLION.....

Have used this a few times. It always shows 0. will be looking for something that works.

After about a month and a half and no longer works it either reads 0 or 99. Junk
