Reading the reviews, I thought it would be just fine for my needs. Indeed, it doesn't provide good measurements. However, it connects directly to the phone, you don't miss anything, and the build quality is very good. With the app, you have many options, but don't expect miracles. It costs €40 and I would gladly pay it again. For this specific one, I would easily pay double. If you don't need step measurements, blood pressure, and blood oxygen, and you're a simple user like me, don't think about it. Just get it.

Very beautiful, very comfortable in the hand, lightweight and at the same time sturdy in construction. Its screen is incredibly beautiful with very bright colors and very good resolution. Its battery, compared to the Huawei GT2 that I have, is I think almost half and a bit more in terms of endurance. Very nice and user-friendly menu, as well as very well-designed buttons, one of which is rotating. There is also an app that, as soon as I downloaded it, did an update on the watch's software. So far, everything is nice; its major downside is in step measurement, where unfortunately things are tragic, and I will give you an example. I wake up in the morning, get into the car, drive 170 km, and as soon as I got out of the car, it had recorded 11,500 steps, and that's why it gets three stars. I hope it gets fixed with some future update because the watch is worth a lot for only €41 it costs.

On the first day after charging from 100, it dropped to 80% in one minute.
There is no sound when a notification comes, only vibration. Sometimes it vibrates, sometimes it doesn't.
The notification comes to the phone, and if it remembers, it also comes to the watch

Step measurements at the wedding of Karagiozis!
Perfectly still and has reached 1000 steps plus!
Don't waste your money!

It is the most expensive QCY thing that puts it on the same level as watches that cost hundreds of euros. It works perfectly on iOS, you make calls normally, it lasts longer than it says and has an excellent screen. It shows Greek in messages, etc.

Very good smartwatch choice for the money.

It has very nice colors and contrasts due to the amoled screen, and the 60hz refresh rate provides very nice and smooth animations.

Sleek and beautiful, it fits well within the steps it displays, and its battery lasts approximately as long as the manufacturer claims.

It has IPX7 water resistance, which means it's not for swimming in the sea, but it can withstand rain and sweat.

The function that activates the screen when you lift your wrist works flawlessly.

The app works flawlessly on iOS at least, which I tested.

At the current price of 37 euros, it is a very good choice.

A similar option that only differs in shape (it is rectangular with a larger screen) is the Gs S5.
