Ketone Breath Analyzer, Ketone Meter with 3 LED Indications for Ketogenic Diet Testing

Well made, easy to use, readout easy to read, good bit of kit.

I've been using this product for about a month and I find it to be accurate and easy to use. This type of technology is sensitive however, and it can give false results. For example strong odours from chemical cleaners, perfume etc can interfere with the reading. Eating or drinking anything other than water prior to testing can also interfere - allow 20 mins after eating before testing. Alcohol consumption can also interfere with results. This isn't conveyed in the instructions, so its worth bearing in mind. What's good about this product is you can test an hour after eating something sweeter than usual, and it can show you how much, if at all, ketosis is affected. It enables one to fine tune a keto diet to specific personal needs.

This is easy to use- all you need to be able to do is press a button and breathe. Simple enough.The problem is the accuracy of the device. I have gone from a level of 1.3 to 2.6 in the space of 5 minutes, with absolutely no change on my behalf at all.What’s even better is that I have literally just done two tests to try and determine what affects it: 0.0 initially, then 3.5 after having a shot of espresso.I now don’t even think this is able to give an indication of whether you’re actually in Ketosis, let alone an accurate reading.I definitely wouldn’t recommend this to anyone who needed to monitor ketone levels for medical reasons. If (like me) you are trying Keto for vanity/weight loss reasons, it is still probably not reliable enough.

This is a fairly precise, useful toy to measure your acetone level when you are on a ketogenic diet.Two caveats:1) It is most accurate when one starts to blow before the start signal (by the beep you must be blowing already).2) It is easily influenced by alcohol, coffee, even water. This is something made mainly to be used first thing in the morning.3) The acetone measurements track several hours what is happening in your body. Hence, it might still give you high levels several hours after a risotto, but the readings will crash the following morning without fail (yes, because of that risotto).A good, efficient device that I would buy again.

Works well

Hard to say if it is accurate, but it seems to work fine, ive read some review that put me off but having read about those keto meters i believe is just a matter of how they work. It seems they use the same sensor as the alcohol meter, so if you drink alcohol for 24h your value will be high ( despite alcohol is sugar so you probably are not in keto), also if you clean it with alcohol. it seems in the morning people may have an higher level of sugar so that may be why someone value change along the day, ive read is better to measure later in the day. also, some food may interfere so , as the instruction actually advice, you should use it at least 20mins after food. Again i am not sure how accurate it is but the value was going up each day since when i started the keto diet, it went up a lot when i drunk alcohol, and it went down next day, so afterall seem to reflect the diet

This is accurate, and far better than the stripe. Many reviews here clearly do not know how to use it, as the instructions clearly state, that you should not use if you have just consumed something (food/drink). This is because it works by detecting the ketones on your breath. If you have other substances on your breath (a fresh coffee) it will give inaccurate results. This is great for people wanting to fast, and see how far into ketosis you are.

Sometimes I question the accuracy as I get different readings. However, this is sometimes due to not have my mouth around the mouthpiece and redy to blow at 0 on the countdown. Breath analysis is more variable but it is accurate enough for me to learn what kicks me out of ketosis and when I need to review what I'm doing with my diet. It is neat and fits in my handbag and so far the battery life seems good. It is very easy to use, so, if you are starting out on a keto diet you may want to get one of these.
