Product description
How to get accurate ketone readings?
1. In order to get accurate ketone readings, please exhaust the residuals completely with the ketone meter before your first use by running the keto breath tester 3 times without blowing,because each ketone breath analyzer was tested during the production before shipping to warehouse, there maybe residuals; if you want to test another person consequently after your testing, please also kindly exhaust your previous residuals.
2. Please blow immediately within first 5 seconds when displaying BLOW on the ketosis tester if you finish the residuals exhaustion step, because the ketone breath tester starts analyzing the breath right after the first 5 seconds
How To Test Your Ketone?
1.Hold the power button for 3 seconds until the device turns on
2.Wait 20 seconds countdown for device warming-up, exhausting the residuals
3.Blow with the mouthpiece for 5-6 seconds, the testing result will be analyzed and displayed on the screen
Kind Reminder:
Readings will be slightly different from the blood meter because of different analyzing methods.
Please catch the same keto meter to track your own personal ketosis records, only in this way you can get your own changing status.
Package Contains:
1x portable ketone meter
10x replaceable mouthpieces
1x carrying string
1x user manual
2*AA Batteries are not included

Great affordable Keto analyzer that appears to be accurate

- Reviewed in Canada on June 26, 2021Verified PurchaseI have been a Keto believer for years and generally have used Keto strips when I felt the need to confirm I was in ketosis. But my last batch of strips just seemed off as they always said no ketones. So I started a hardcore diet for the past week 8g of carbs a day to ensure I was in ketosis losing weight during that period etc.
Using the strips NO Ketosis...
Ordered this handy little analyzer of Thursday, recieved it on Friday (nice fast delivery 😎).
I immediately popped it open and put in some batteries. Which leads to my only complaint. The battery compartment is hard to open, I had to grab a butter knife to help open it.
Staring the unit is a bit tricky as you have to press the start button for a second or 2 no quick press. I actually prefer this once I figured it out as it will help preserve the battery.
Once started the unit does a 20 second count down to 0 than who breath (not blow) into the unit. My Friday afternoon reading showed 1.4 so as suspected I was in full ketosis!! My Saturday morning reading showed 1.8.
So I now have an accurate (as compared to Keto strips) way to confirm Ketosis. This is important as I will now adjust my carb level higher to allow a wider range of foods to ensure I get the right micronutrients while maintaining my macros.
I highly recommend this unit, as the blow pieces seem to be snug enough, the unit appears to be accurate, it has an easy to read display with color coding for ease of use, auto shut off for battery life, and a nice simple draw bag to hold the machine.

- Reviewed in Canada on February 5, 2025Verified PurchaseThis should be more of a toy, as it works intermittently. You can try it in the morning before food and it gives a reading sometimes, then 10 min later nothing.
2 day water fast and machine reads 0 ppm
- Reviewed in Canada on June 8, 2025Verified PurchaseIt worked well for the first few months and still semi-works occasionally. The issue is that it needs to emit a long beep to indicate it's analyzing, but most of the time it just gives a single beep, you blow, and then it beeps again and shows 0. However, if you try it multiple times and finally get a long, continuous beep, it will take a reading.
Basically, I have to try 4–5 times before it works. I’ve tried blowing hard, soft, and medium—nothing makes a difference. I thought the issue might be me, but I’ve changed the batteries, and now, after 8 months, it doesn’t work at all.
When it worked, it was great, but if anyone knows what the problem might be, please let me know—otherwise, I’m ready to toss it in the garbage.
- Reviewed in Canada on December 17, 2024Verified PurchaseMonths of on and off keto and still works well. When on keto, I use it a LOT. I had used blood testing previously, so I know actual ketosis. Done with strips so could not do direct comparison but when I FIRST began using this meter I was HIGHLY suspicious when IT WAS GIVING ME "0" when I thought I should be in ketosis. Stayed in fast till next day and there it was, sensors work just fine. I recommend this model.
- Reviewed in Canada on July 30, 2021Verified PurchaseI've been on keto for 8 days with minimal carbs (less than 15g/day)
I tried this a few times, the acetone results range between 11-19ppm which indicated I am in the optimum level of ketosis. One thing is that I can't seem to find where I could change measuring unit to mmol/l for ketone level. Nothing in the manual, kinda odd since other reviews picture
showed mmol/l
I tested with a person who isn't no keto and glad to see that the result is 0 ppm.
I hope the meter will continue to work.

- Reviewed in Canada on June 21, 2023Verified PurchaseWasn't able to check reading accuracy so just going to assume it was close if not correct.
Bought in January 9, 2023.
Stopped working June 20, 2023.
Worked six months and stone dead now. Item was babied, funnily enough, kept in bathroom vanity drawer.
One star for garbage product life.
If the item kept working it wouldve been a great tool to help us stay on the straight and narrow.
Glad we are a wait for awhile prior to review.
Hope this helps someone in their decision to purchase or not.
- Reviewed in Canada on January 23, 2025Verified PurchaseI tried using the strips to see if I was in ketosis and they never changed colour. I bought Breathaliser (spelled wrong), hit the button for the timer when it beeps you breathe into this compact machine, when it beeps again u have your reading.
- Reviewed in Canada on March 28, 2022Verified PurchaseThe product look and is boxed very professionally however the instructions are a little lacking.
We were almost about to box it back up as defective after trying several pairs of batteries when we realized you need to hold the power button for several seconds.
IF worked well for the first couple of weeks and now we have noticed that it is very hit and miss to get the tone and a measurement regardless of how hard or soft you blow (or if you run the machine without blowing multiples times first).
