Ketone Breath Analyzer, Ketone Breath Meter Portable Digital Ketone Breath Test Tracing Ketosis Status with 10 Mouthpieces

This product seems to be good enough to tell me if I’m in Ketosis, but once I’m there, readings are all over the place. It’ll show 9.0 one minute. Then 5 minutes later I’ll blow a 4.0. Each time is dramatically different. But if I’m definitely not in Ketosis, it seems to give me a consistent 0.0. Seems like a yes or no readout would be more appropriate for this device.

To allow this meter to really do a great job of reading Ketone levels, follow these rules:1. DO NOT take a deep breath before blowing into the meter. Take shallow breaths as the countdown approaches zero and then do an extended exhale into the meter for roughly 8 seconds. The big breath brings in fresh air and does not allow the ketones in the lungs to be measured.2. Shake the meter a few times up and down (slowly) before using. This helps clear the meter of old air and usually stops the meter from doing TWO twenty second countdowns.3. Don't worry if the meter shows zero occasionally. Also, don't worry if it shows zero for the first day or two on a Keto diet. Give it a little time and follow rule 1.

At first I was not getting reliable feedback from this. I have been on a Keto diet for well over a year. I started with the test strips but after a while those stop working correctly and you either have to do blood tests or breath testing to get a better indication. My first readings were wildly erratic - starting out at 1.5 (good!) and successive tests being well off the original and some even reading zero. I contacted the seller and was given this advice which seems to stabilize the result:1. Run the unit 3 times without a test (do this by pressing the start button immediately after you get a zero reading, the unit will immediately cycle through another warm up.2. On the 4th warm-up, wait for the count down and when it beeps blow through the tube EASILY. You're not trying to blow up a baloon. Just a soft steady breathe into the device.3. The device will beep again. Stop blowing and it will process the results. I'm able to get steady reading using this method (usually within 0.2 points of each other.Other pointers. - don't use right after a meal. Use first thing in the morning (or before ending a fast).REVISEDAfter taking into account ALL of the recommendations from the manufacturer and trying two of these (side by side comparison) I can't recommend this as a reliable measurement for ketones. I've sent it back. I got distinctly different reading in the side by side tests AND I've asked friends who are NOT on Keto to try it and they are registering as if they are on the Keto diet. You'd be better of wasting your breath on a balloon.

She worked fine for me. Definitely better than the urine strips. The one I had started acting up on me which forced me to return it. I am sure since so many of these were sold that it was just my unit with the issue. I would buy this again.

I thought this was great until yesterday. It worked well for about three months. Yesterday it started reading no breath at all as having above a 3.0 ppm. I noticed a low battery indicator. I thought this would be the solution but it has not changed. I’ve continued to check over the past 24 hours. Now it will read the first reading, with no breath at all, as 0, but the next reading is 1.0, still with no breathing into the monitor. I hope someone can read this and explain to me what is up so I can continue to be happy as I was before.

If you are considering purchasing a ketone breath analyzer, this one is definitely a good choice. It's much more accurate than urine sticks, it's also a much better investment and produces less waste. Of course, it's accuracy is what is important and it definitely does the job.

I've never wrote a review before but I'm compelled to do so here in hopes that others won't waste their money on this junk.When I first unboxed and started the monitor it all seemed to be working well, and the readings came out to be about where I thought they should be given my state of ketosis. This only lasted for a few tries however and now (literally not even a day after I unboxed it) the readings are either a 0 or 9.5...my wife, who isn't in ketosis, had her reading come in at 9.5 (which is when I knew something was suspect) and regardless of how many times I restart, remove the batteries, change mouthpieces or try to retest with my own breath the readings are only at 0 or 9.5. I have been in ketosis almost 100% of the time now for around 9 months so I will know where I should be given what I've eaten and so on.The long and short of it all:THIS IS JUNK --- DON'T WASTE YOUR MONEY

Great
