Blood Sugar Blood Pressure Heart Rate Blood oxygen Sleep Monitoring Waterproof Smartwatch | Carelders F57

A slim, lightweight digital watch that’s easy to use and includes activity tracking. Seeing the numbers go up while running gives you a real sense of accomplishment.

Marveled with this watch.
It's the first smartwatch I own and I'm really surprised.
It has all the typical functions of these watches, related to health and sports. It tells you the daily steps, whether running or walking, the calories, etc.
In terms of health, it makes a lot of measurements, which I honestly don't know what level of medical reliability they can have, but it really has a lot of options, as seen in the video.
For me, the most useful applications it has would be mainly calls, being able to answer calls and talk from the watch is very useful when your hands are busy or dirty and you can't pick up the phone, in those cases I use the watch. I have to say that the sound quality is perfect, you hear very well and they hear you as if you were hands-free on the phone.
It has other very useful applications such as reading messages. You configure which messages you want to reach your watch.
Finding the cell phone, this is one of my favorites...
But it has infinity, the time, calculator, alarm, stopwatch... it wouldn't end.
Using an application that you download to your mobile phone, you can configure the different options, such as wallpaper, battery savings, etc.
In terms of battery life, it lasted 4 and a half days and I put it to charge when there was still 15% left, so it would last 5 days and considering that the first few days you don't stop researching, you use more battery than usual, so 6 days can last.
It charges fully in 2 hours.
I tested the water resistance by scrubbing or washing my hands, I haven't submerged it just in case... but so far so good.
The strap has a soft feel and is very easy to fasten.
The size is just the one I like, bigger I wouldn't wear it and actually smaller it costs more to read...
You can put the menus in Spanish, but yes, the translation is not very good in some words.

All in all very good, I recommend.

This watch is absolutely stunning for the price, offering the sort of functionality that you expect from much more expensive makes and models!

I have this to my brother as a gift since he broke his own and he was blown away at the quality, and the wife range of watch faces and health/fitness metrics available.

It was so good I tried to buy another one but they'd already sold out!

Great battery life, data tracking that's comparable to my Garmin smart watch, smart looking and easy to set up and use - a perfect budget smart watch.

Impressed greatly by this smart watch, it connected so quickly and easy to use and set up,with great battery life and many useful features the screen is clear

Very easy to use watch.

Very good value for money
