First of all, I want to say that it is beautiful, very elegant and discreet with good construction and quality materials. I got it with the black strap as it comes in its packaging.
It is absolutely worth the €35.
Things I liked:
1. It is very easy to wear and take off and does not tire you while you wear it.
2. It is waterproof.
3. It has a fantastic screen, small but readable and bright.
4. It has a function that reminds you every hour of inactivity to get up and move. I have activated it because I do office work and it helps a lot.
5. It has a workout function that counts the steps you take, your heart rate, the heart rate zones you enter, the time you maintain in each zone, and the calories you burn.
And I want to emphasize this point. Whatever exercise I do (crunches, weights, cardio, etc.), I activate the walking function as exercise. This way, I have the data readily available on the screen (heart rate, calories, etc.). This helps me a lot to maintain cardio in the second zone for fat burning or to move on to the next set after my heart rate drops.
6. You can also measure your oxygen and stress levels.
7. And the simplest thing, you can see the time at any moment.
Also, by wearing a wristband, you can wear the band higher on your arm and it still measures correctly. I didn't expect that.
However, the step measurement is not that reliable. I have noticed that it misses about 1/3 of the steps and does not count them. It mainly has to do with the movement of the arms while you walk. If you walk without moving your arms much, it does not count the actual steps you have taken.
Also, the calories it measures are approximate and far from the actual calories you burn, mainly during inactivity and sleep. During exercises, it measures them more accurately.
I do not regret buying it; it is very useful, especially during workouts.
