Coolker Ketone Breath Analyzer Professional Grade Accuracy Digital Ketone Breath Meter Tracing Ketosis Status with 10 Mouthpieces(Black)

I suggest reading instructions well before using device. This is my first time using one despite many years of keto. Don’t want to track every morsel and this seems to let me know if I had too many carbs or hidden carbs while dining out. I can be obsessive so I find that testing once a day, first thing in the morning is best for me. It is easy to use but waiting the 20 seconds can prove difficult with ADD; I realize I’m spoiled in a world of instant gratification

got my meter today, been running comparisons between this and my Keto Mojo, after several tests side by side the breath analyzer is very close, if not right on the Keto Mojo readings. Take the accuracy along with the reduced cost and there is no reason to go with a direct blood meter when the create analyzer is so accurate and convenient

I bought this for motivation. I find when I am thinking of skipping I take a read using the device and think I don’t want to start again for that treat. It really helps me stay on track. It also really is satisfying to see when I hit the green numbers because it reinforces I am in the right track instead of wondering. After practicing on the device a few times you get in a rhythm and it is really easy to use. I almost spent 100-300 on other devices that I saw on utube and reviews were accurate when compared to blood testing. After seeing several reviews that this was also very accurate I bought this and I’m glad I did because for me it is more of a motivational tool. It fits into my purse and came with a little bag so very nice and more value than I expected for the money. I also love that it will power down on its own after a few seconds.

I loved the ease and convenience of a breath based ketone monitor. Much simpler than getting a blood ketone reading and I was looking forward to not having to do a finger stick every time I wanted to check ketones...... if only it was accurate. I added a comparison video of this breath ketone analyzer at the mmol/L reading and the Keto Mojo blood test at mmol/L. I’ve never had any reason to believe that Keto Mono monitors are inaccurate. So, when I compared the 2 readings side by side and the breath analyzer was about .5 off from the blood test, I knew this product wouldn’t work. When doing keto, every tenth of a point matters, so being off by so much makes this breath analyzer a complete waste of money.Definitely do not recommend.

update: received replacement meter…it is soooo off!! readings are 6.2 - 6.4 ppm, other meter reads 13.7 & 14, i’m always around or above 13.7 and since i tested first meter with a friend’s breath meter, i know the 13.7 and up is the accurate one.. these simply are not reliable, under 8 would mean i am not fat adapted/burning fat and hmm i know that is bull!! lowering rating..was great and overall accurate until it decided to start doing a double error beep 4-5 or more times in a row before it would actually do the constant beep to analyze your breath.. first it was once and within a couple days it became constant. not a battery issue, they are fine and i even changed them just incase because some meters will misbehave when batteries get low.. so product is good until 3-4 weeks of use it seems, thankfully for me, i still have 6 days to return it and since i did like how it worked, i’m given it another try by having it replaced for it was a good breath meter when worked..NOTE: some think this meter was not accurate cause their blood meter showed lower/etc. readings...BREATH meters test how well you are utilizing/burning fat, not how much ketones are in your blood!! you CAN have low blood ketone readings once keto/fat adapted and still be burning fat..hence where breath meters become useful, especially during fasting/AM’s..
