EEK-Brand Ketone Breath Analyzer, Professional Grade Ketogenic Diet Tracing, Ketosis Status, 10 Mouthpieces(Black)

The product does exactly what I need. I am very pleased with the product. It is easy to use and the instructions are very simple.I am very happy I purchased this product

Constantly showing 0 or 0.0 on both modes. Terribly instructions provide 3 different length of time you need to blow for, and no clear guidance on when to blow as many customer feedback comments already state.For the price of this product the least the seller can do is make sure it works before it gets shipped.Refund requested, do not waste your money on this product or seller.

I gave 5 stars for accuracy as seems to work well,the longer I use it the better I get at keeping in ketosis, but have no way of knowing how accurate it is.I didn't want to give a poor review as think it is a good product.

This Ketone Breath Analyzer is simple to use & comes with 10 replacement mouth pieces. Just press button for 2 seconds to switch on, wait for the countdown to finish (20 seconds) then start blowing for between 3-6 seconds (depending on which part of the instructions you refer to. One section states blow for 3-5 secs, whereas another section says 5-6 seconds. However the instructions also blow whilst the 'dashed square symbol' is displayed and until the 'dashed straight line is displayed. This proved a bit difficult as you cannot see the screen when blowing but by trial & error I found that you need to blow for about 8 seconds. after another few seconds the display shows the result in mmol/L (millimoles per litre) but it can be altered to ppm if preferred. It is quite expensive so hopefully the readings are accurate. If you get an unusual or unexpected reading you can press the power button once & it will reset to the countdown stage and you can have another go. There is no limit to how many times you use it and it remembers the last 32 results so you can look back & see how it has changed over the period. If you do not touch anything it will auto-switch off after about 15 seconds.

Great

I've started Keto Diet for health reasons a while ago and wanted to test ketone levels but not keen on dipping strips in urine every time. This monitor is great. Very easy to use. Just pop the batteries in, press "on", wait for a few seconds and blow on the mouthpiece (10 provided) for 5 seconds and you get the result. Difficult to say how acurate they are without some other method to compare but I do notice changes according with my diet.My only criticism, I would like a "beep" when the result is ready. My monitor never did it regardless how long I blow in the mouthpiece. Comes with 10 mouhtpieces but they are reusable. Also comes with a nice pouch to place the monitor after use.A bit more expensive than a pack of strips but will become a better value with time. As saves you buying more and more strips.Really pleased with it.

The media could not be loaded. Arrived with broken casing. Gave reading of 0.1 to 0.3 even after doing recommended null reset process. An absolute waste of money. Stick to the ketostix.

I found it to be inaccurate and not worth the bother. Instructions are non existent so I had to go on line to see how to use it. Not a great buy
