  • Battery Life

    Battery life shows how many days the smartwatch can operate without charging.


    It depends on the battery capacity, but also on how much you use it (e.g. active display, GPS, notifications, etc.).


    For example, a smartwatch with 2-3 days of battery life is ideal for daily use with all features enabled.


    Models with 5–10 days or more are suitable for those who do not want to charge often or use it more "lightly".


    The value is especially meaningful when comparing products from the same manufacturer.

  • Display Type

    IPS

    IPS technology is a type of screen that offers wide viewing angles and vibrant colors, ideal for a clear image from any angle. It is suitable for users who want quality display in everyday conditions. They consume more energy compared to OLED, AMOLED & super AMOLED types.

    For its price, it is excellent (I got it for around €40).
    Personally, I use it as a daily watch for the gym, etc., and it is very convenient for the stopwatch, music control, and notifications.
    Also, I like the design quite a lot as I wanted it to look as much like a regular watch as possible.
    Finally, another positive point, which I didn't expect, is that it has a very good speaker and microphone for calls.

    However, it has the following issues that personally annoy me:
    1) Firstly, for Instagram notifications, it doesn't show you who sent the message (though I don't know if this is a problem with the app itself or the watch).
    2) When you start recording an exercise, it doesn't let you use the watch for anything else except music control. It would be useful if you could also use the stopwatch, notifications, etc.
    3) You can't set it to silent (vibration) for incoming calls. Also, it's very annoying that sometimes, even after you've answered the phone, it keeps ringing until you stop it from the watch.

    It does everything it promises. Strong battery, calls from the watch to 100 contacts. Heart rate, oxygen measurement, sleep, menstrual cycle, faces for all tastes. Notifications for many applications besides TikTok and Outlook. Overall very satisfied for a watch under 40 euros. 39.90.

    This review is about the colour: Silver

    Positives:
    1) It will definitely satisfy you with the updates you will receive. That is, the vibration for calls or messages will ensure that you do not miss notifications.
    2) Its speaker is extremely loud and you will hear it crystal clear, as well as its microphone.
    3) The battery seems to be quite good.
    4) It supports Greek letters, has a Greek menu.
    5) It has a pulse oximeter.
    6) The app is quite good to the point of being comparable to other more expensive ones.

    Negatives:
    1) It is difficult to read any notifications in Greek due to the difficulty in displaying them with the correct spacing. Of course, for €60 you can overlook this.
    2) Few options for backgrounds.
    3) Basic apps are missing as options to receive notifications (e.g., Outlook, TikTok).

    Conclusion:

    It is worth buying it on the condition that you spend a little money and purchase a product that so far seems more expensive.
