The scale is beautiful. High-quality construction, accuracy in measurements, user-friendly. A button on/off designed to open with the big toe without bending or applying force. The buttons are very high-quality, as well as the screen. The body fat measurement is precise. One issue is that while it has a previous measurement, it only applies during the body fat measurement and not during the regular measurement. Another issue is that while the regular measurement shows 72 kilograms, the body fat measurement shows 700 grams to 1 kilogram more. This is because when doing the body fat measurement, you hold the screen in your hands and the screen weighs 300 grams. The screen is connected to the scale with a spiral cable that acts as a spring. The more you lift the screen, the more it stretches and weighs. Of course, this does not affect the body fat measurement. Therefore, someone should weigh themselves twice. Once with a regular measurement, where they will have a very accurate body weight measurement, and once with a body fat measurement, where the body weight is not taken into account.

The only disadvantage I can mention about this scale is that its manual is in English and other languages, but not in Greek. However, this is an easily solvable problem as you can find it on the internet and download it.
I mention the manual because it is very important to read and understand the theory behind the measurements. I say this because before buying it, I read some baseless negative comments.
The scale is excellent and very reliable. It has repeatability in its measurements when they are taken during the same time period and under the same conditions. In fact, someone can draw many conclusions about their metabolism by taking multiple daily measurements (four as recommended by the manual) and help their body lose or maintain weight in the right way.
The scale self-calibrates every time we weigh ourselves. I compared it with other calibrated scales regarding weight and it is absolutely accurate. It is good to have it in a stable location and not move it from there. For measuring body fat or muscle mass, it uses electrodes on both the hands and feet, which shows that it takes into account water concentration during the day (detailed in the instructions). I highly recommend it.

The scale self-calibrates every time we weigh ourselves. I compared it with other calibrated scales regarding weight, and it is perfectly accurate. It is good to have it in a stable place and not move it from there.

Very good build quality. The measurements of body fat, muscle mass, and visceral fat are extremely accurate if the instructions are followed. It is truly a great help for anyone on a diet or doing intense workouts. And the price is reasonable.
I would like to add (after 5 years of use) that what other users write in their reviews is true. The measurements are not always the same and there is a range of values that depends heavily on the body's hydration level. I have been using it for 5 years now and I know when... it deceives me!
For example, in the summer, when I generally have less fluids and I am more dehydrated, it shows my body fat as 11% while in the winter it shows 14%. For many, this difference in measurements is unacceptable, but all indirect measurements have fluctuations even within the same day. I do not consider this a problem. Generally, I understand when I am retaining fluids, and even if I measure the folds of my skin with a caliper, there is a difference depending on my diet, fluids, and salt intake. The measurement changes if I measure myself after a workout or a run. The scale calculates body fat indirectly and therefore gets confused depending on the body's fluids since it calculates muscle mass and fat in combination. So whenever it shows lower fat, it increases muscle mass and vice versa. This is, of course, a matter of inaccuracy, but with a deviation of 2-4%, I do not consider it unacceptable.
However, the scale is used in the long term. When I started, I had 37% body fat (+/-4%) and now it's 12% (+/-3%).
So it does its job. I know where I stand! If anyone is looking for greater accuracy than this, please let me know! I also get body fat measurements done by professionals once a year, and they coincide with my scale's measurements. One issue is that if you are overweight and lose weight, then the skinfold measurement shows inaccuracies as there is excess skin. Ultimately, there is no absolutely reliable method, but the average guides you in the long term.
The most accurate measurement, however, is ONLY DONE IN THE MORNING after waking up and using the bathroom. Getting on the scale 3-4 times a day at different times, of course, gives different results and you don't know which one to believe. The low or the high? Haha... whichever is convenient?
Things and measurements take time, not hours!
