I didn't exactly buy it through Skroutz, because my brother gave it as a gift to our parents. So, two were purchased from England. I came to evaluate and inform that this watch sent a notification to my father that his heart rate dropped to 45 last week. It shows me and tells me something is not right, I will go to the doctor, he goes to the cardiologist and they urgently give him more tests. I don't need to elaborate on the problem; his condition was very critical and he narrowly escaped a heart attack!!! I have to share with users and anyone thinking of getting it that this watch saved his life! All the doctors said he survived thanks to the watch! Now he is well, and my brother and I owe at least gratitude to Apple!

It measures quite well, syncs perfectly, the battery lasts for a day and a half with full notifications, it doesn't last any longer, but no Apple Watch that I have worn lasts more than 2 days max, so for me it was expected... I am slightly bothered by the brightness, I would like it a little bit higher.
The use I make of it and the reason I bought it is to track my workouts, so my needs are covered. If you want something extra, something more, it's better to look at the other Apple models. However, for iOS users, it's the only way to go because of the same software compatibility, since you have your phone in your hand essentially
