Ketone Monitor Device Testing Breath Ketone Content with 32 Recent Testing Records

Tested it after different meals and it was inconsistent and wrong. I ate a bunch of stuff that would have definitely knocked me or if ketosis and it still said I was in ketosis.

Been using it close to a week now, near the start of a keto-diet. While I can't attest to the accuracy of the device (how closely it's measurements match a "gold standard" reference test), I can tell you the precision (how tightly grouped are several measurements taken with this device) is fantastic. I can report the same observations as others, which is that breathing into the device at the start of the exhale will give lower readings than breathing into the device near the end of a breath. Others have stated that using breath near the end of your breath more closely matches blood readings, so this is what I've been doing. That is, breathing into the device when my lungs are nearly empty. The precision of several readings is awesome! And you can watch the ketone levels rise as a day of fasting progresses. I love this device. Had no idea a breathalyzer could work so well for ketones. Definitely worth the money.

I just received it today (7/12/19) and my readings have been all over the place... from .2 to 2.5. Not sure if I am doing something wrong so I am going to give it a few more days and compare the results to my urine test strips and see if it becomes more accurate! I will post an update in a few days!

I received the monitoring device yesterday 07-05-19 and Blew a 1.5 yesterday and a 1.4 today, which places me in full Ketosis. Easy to use. Keto strips are inconsistent, and blood test inconvenient. I like the results of the monitoring device so far. Thanks.

Very simple and easy to use. Seems accurate in that I can see very specific changes depending on what I have eaten. My only complaint is that when you are blowing into it, you can't see the display and it doesn't give a tone when it has a reading ready. I have to hold my hand up near the display to see when the color changes so I can stop blowing and read the measurement.

Take two tests successively with a gap of 5 minutes. One shows reading of 1.9 and the other shows 2.8.Not reliable.

Very inaccurate. Returned the first one for not working at all. This one is all over the map, while testing strips are consistent. Save your money

I use this everyday. It is quite accurate. It is simple to use. The information I receive is so important. This device has helped me to be relaxed while I stay in the Keto zone.
