Ketone Breath Analyzer [New Version] Portable Digital Ketone Breath Meter Tracing Ketosis Status with 10 Mouthpieces

The entire purpose of buying a device like this is to really understand where you're at in terms of ketosis. I received an elaborate set of supplemental instructions for how to use the device, presumably because of bad feedback on the product. I did exactly as instructed, including the pre-work suggested for overriding incorrect readings that may result from the factory testing. That alone is weird. They say it's up to the user to reconfigure the device to account for their testing.My first reading was 3.0, which is borderline starvation. I waited (as instructed) between use. Again, weird that you have to wait 3-5 minutes between tests for the device to re-set itself. I ran between 2.4 and 2.8 for several other tests. I had just started the Keto diet and was not overly strict, and there's no way I was in starvation mode. I had my wife test it. She was also not starving but was coming in in the upper 2's. I had my teenage son try it. He had been eating pizza and drinking soda. He was 1.8. My other two adult sons eating regular carb diets both registered at 1.4 or higher. For reference, the sweet spot for ketosis is roughly between .5 and 2.0, and it's pretty difficult to get there. You don't just stumble into ketosis.Tried again a few days later after falling off the Keto wagon and still had wildly inconsistent readings from 1.4 to 2.8, which would have been impossible.Finally got to a point where maybe the readings made sense. Maybe. I was coming in at .4 and my wife was a bit lower. But how can you trust this device after all of that. And the supplemental instructions were so crazy about how to get the right readings, e.g. you have to figure out how long to blow for your particular results. Some people need to do it longer, others shorter. You have to do it in the morning, which they claim is when you're most likely in ketosis, but many experts say the evening is the best time to measure you levels. Don't drink or eat within x amount of time and so on.Bottom line is that even if this device works, there are just way too many variable that are going to impact your reading for you to be able to really track progress. You won't know if it's the device or the way you measured it or your actual Keto state reflected in the readings.

The media could not be loaded.  I purchased this meter because ketone urine test strips only show the ketones that your body has gotten rid of. They don’t show the ketones that are currently in your bloodstream. This ketone meter has been accurate, easy to use, and very easy to read. I blow into the meter at the same moderate rate each time, and I always blow for a count of five. If I want to do a second reading after the first, I wait a few minutes, turn on the meter, let it cycle completely through and make sure that it shows a reading of 0.0 before I begin the second test. In doing this, I get consistent readings. I take readings at the same time of day each day for comparison purposes, but I like the fact that I can easily take a reading as many times as I want during the day. I have included a video that shows how to let the meter cycle completely through until it shows a reading of 0.0. I then restart the meter, and after it’s counted down to zero, I blow into it and get a reading of 1.4. Note: Some reviewers are getting inconsistent readings. I believe this may be because they're not waiting long enough in between tests. It takes quite a while for the meter to clear after a test, five minutes or more, in my experience. Cycling the meter does not help clear it. As long as I wait until the meter shows 0.0 after my first test, the second test result will be consistent with the first.

Edited review. This thing always shows in ketosis even even when no one is blowing in it. It doesn't work even a little bit. This is a HUGE waste of money. DO NOT BUY. Now I have to throw this one out and try to find one that works.Old review. It keeps showing .1 when no one blows in it, or when my husband who doesnt do keto blows into it, so I cant tell if my higher score is accurate. I may have to send it back :(

Works so great and super helpful tool for my keto journey! Highly recommend!

Everything about this product is great, except it doesn’t work. If no one blows into it it still reads anywhere from 1.0 to 3.0 I will run it five or six times with no one blowing into it to try to get all the residuals out and it still doesn’t come all the way down. It is too bad because it is very easy to use.

This particular meter did not work for me.

Works as advertised. Nothing to complain about.

Have only had this product for about 2 weeks. Absolutely love the ease and accuracy of the unit. SO much better than using the urine strips. I highly recommend!
