I have had the Amazfit GTS 4 in Autumn Brown color for 9 months now.
I had experience with similar gadgets like the Razer Nabu and Razer Nabu X, which were Activity Trackers. Then, I had experience with an old MyKronoz watch that cost around 100€ at the time, and before that, I had been using the classic Amazfit Pace with the red strap for years.
I am very satisfied with the Amazfit GTS 4 because:
1. It has never lagged so far.
2. The strap is like a fabric "scratch-scratch" and not silicone, which makes it sit perfectly on the wrist, not bother during sleep, not make the hand sweat, not cause allergies, and not cut into the skin. It is also very easy to clean.
3. Like other Huawei watches, it has countless functions and applications that help in daily life. For women, there are even applications related to gynecology and a helpful event tracking application for pregnant women. It even has mini-games if you are bored and don't want to take out your phone. It has an app that syncs with Google Maps, although I haven't used it yet.
4. The fact that you can make and answer phone calls with it has been a lifesaver. Whether on the road, in public transportation, at work, or even in the car, you don't have to search for and take out your phone from your bag or jacket. It's a savior.
5. The screen is enjoyable and doesn't strain the eyes.
These are the most basic features, and I have more, but to summarize:
The touch responsiveness of the screen is fantastic, just like using a mobile phone.
Instant connection with the phone, although I don't know if it matters, I have the OnePlus 7T Pro.
Sleep update and reminder.
Vibration alarm.
Vibration to find my phone, even when it's on silent.
Vibration function to remove water if it gets into the speakers.
Music playback.
Battery saving mode.
The battery, in normal operation with Bluetooth always on and regular use, lasts over a week until today.
Adjustable brightness from very low to very high, allowing 100% visibility in bright daylight.
It also alerts in moments of anxiety, warning you to inform those around you to be careful and helping you control the situation as much as possible with breathing exercises.
One negative thing I had was that when I bought it, there were no cases or screen protectors available. There was only a membrane that permanently created four bubbles, one in each corner of the screen.
I highly recommend it. Now, when I don't wear it, for example, if I forget it after taking a shower, I feel insecure as if I don't have my phone with me. I bought it for 150€ at the time, and I'm considering getting it as a gift for my partner.
