I bought it for my wife, so I can't be 100% accurate. As a battery, it lasts 4-5 days with all functions active. It's not at the level of Huawei, but also not as bad as Wear OS watches. The screen is quite clear, but the Greek translations of the menus are a joke (you have to switch to English at the beginning to understand what the poet means). I don't know about durability (and I don't want to find out). In terms of appearance, it looks more like a beautiful piece of jewelry than a smartwatch. The last negative thing my wife has noticed is that due to the material it is made of, it gets dirty underneath more easily than the previous smart band.
