I will be as objective as possible. I was given it to monitor glucose levels during pregnancy.
Positives: The use of Bluetooth with the app is very useful, especially if you don't want to carry papers.
Negatives: It shows random readings. It doesn't have a consistent deviation and generally sometimes shows higher, sometimes lower, without knowing what's going on. A characteristic example is the glucose curve, which showed 96 at 0 minutes while I had 83, and 100 at 120 minutes while I had 105 (!!!). I do not consider it reliable.

just stay away! the measurements are completely wrong... you put one strip to measure and immediately put a second one and it shows +15. you shouldn't mess around with these, don't waste even a single euro on this

the most stupid thing I have ever bought in my life to measure my father's sugar, I wasted too many strips, even extra ones I bought, nothing worked

Very good, easy to use and the BLUETOOTH works perfectly..
With another one I have, they don't always give the same measurements. But this one has small deviations in daily use. While the other one has large deviations. I think it is a very good purchase.

I did a glucose tolerance test at a hospital. After one hour it showed 184 and the lab results came out at 120... it always shows higher and in the morning measurements it shows around 90 while from lab measurements I had 80... I believe I always have less than what it shows and I just use it to confirm that I am not exceeding the limits by much..

Very good measurements. It was verified with immediate blood sugar tests in a laboratory and the results were similar.

I struggled a lot until I realized that I shouldn't touch the blood drop on the surface of the strip but on its edge.
The device turns on automatically when you insert the strip and the measurement is automatically recorded in the app without needing to open it.
So you don't have to look for how to activate the bluetooth—which isn't mentioned anywhere in the tons of instructions—you need to hold down the up-arrow button for 3 seconds.
When you download the app (Contour), it will guide you.

the best sugar measuring device! I did a test using the device with the measurement from the diagnostic center and they had only one unit difference. The test was done using the same blood and not by pricking the finger so that I have more accurate results.

I am not the most experienced with blood sugar measuring devices but this one is reliable. On the day I was going to have blood tests at a laboratory, I took a measurement with this device in the morning before I left. The measurement was the same as the laboratory results.
It inspires confidence. I recommend it.

Positives:
I got it to check my glucose levels before and after exercise. Recently, I had a measurement done in the lab. After using this device, I was satisfied with its response after eating as well as before it. I took continuous measurements and noticed that my blood sugar dropped after eating.
In a morning measurement, I took 5 consecutive readings and found that there was a deviation of 2 to 3 units from measurement to measurement. I consider this to be normal.
Negatives:
It could have a button to eject the strip. But you pull it out by hand, it does the same thing.

I give 4 stars to the fact that on the same day I measured my blood sugar myself, it showed a value of 82, while on the same day at the microbiological laboratory, the value showed 93. I don't know how reliable it is, because the difference is almost ten units. Otherwise, it is user-friendly.

It gives 10 units above the free style meter. I don't have a picture yet of which meter is deviating...

I consider the plant to be good, but many times it gets stuck and even though I give blood and wait for the results, it closes on its own instead of producing the results after an hour.

5 stars for the price. I had no idea how the measurement works, so it took me a while to understand that you touch the end of the tape to the droplet. I don't know if this is how it is for all, but this part requires great precision and improvement.

Easy to use and currently reliable.
In consecutive measurements, at the same time, it gives a small deviation. I have taken measurements that I have taken from time to time and in external laboratories. I consider it reliable, however, I will continue to check it.

Very good products. I purchased the bundle that included the machine, lancets, and blood glucose test strips for my grandmother, and we are
satisfied with all of the products. I will purchase from this store again.

All sugar machines steal this in the sugar curve that I make, it steals 1 unit more. While in the hospital it stole more than 10, it is quite reliable

Quite easy to use. Inside the box, there were also some nails, 5 or 10 (I don't remember). So, along with this, I also bought some extra nails apart from the tapes.

Very good and reliable machine especially compared to others on the market! Minimum blood test rejection!

With a difference of 20 minutes that I gave blood for tests, I also took a measurement with this specific meter which showed 106, while the tests showed 88

Very good! The results are automatically saved if you have your mobile phone nearby via Bluetooth. The application is very helpful as it creates your blood sugar curve for you. You can also enter emergency contacts if the value is critically low so that your loved ones can be informed. It is also compatible with Apple Health, etc. Another great positive is that the test strips allow you to add blood if you haven't put enough, so the strip is not wasted like in Wellion Calla Light, for example.

All machines do the same thing otherwise it wouldn't be a machine for sugar but something else. However, this specific one does more than just displaying the measurement and noting it on paper. You don't need to keep a handwritten diary for the prices and the time you took the measurement, additionally add what you eat, medication, photos, and activities to the result of your measurement for a complete digital diary that you can print. You just need to connect it to your mobile.

Reliable measurements! I took a measurement with the same blood sample that was taken for my glucose curve at the microbiological lab, and the deviations were minimal, around 3-4 units! But why would anyone buy it when they give it for free with the test strips?

Accurate measurement (compared to a microbiologist's measurement that same morning). Affordable, easy to use, and reliable.

It is not stated anywhere that it is Bayer, easy to use, has Bluetooth and connects to the mobile phone, the package includes the machine, the piercing pen, a case, instructions, and some lancets and measurement tapes for the first uses. I consider it a very good choice

I compared it to mine, it took my blood and showed +17, and in another comparison I made with a different machine, the deviation was even greater, so as I got it, it's going for recycling

The negative aspect that I point out is that it was tested at a diagnostic center simultaneously with the same blood and it showed 15 units higher on the machine compared to the laboratory price.

Easy to use, practical, and useful connection with the mobile phone. The measurement is relatively accurate. I measured 1-2 hours before I had a regular blood test, and the values were very close.

Reliable..of course, pay attention to the quantity of blood...I took a measurement before getting blood tests and it came out exactly as the machine showed me one hour before the examination.

Amazing! Perfect results with a small amount of blood and in combination with the mobile application, it helps you a lot!
