I have been exceptionally impressed with this watch. All the advertised features work as promised (rare!) and the app is easy to use with almost all the data collected, processed, and displayed in very thoughtful and intuitive ways.
And it collects so much useful data - far more than most fitness trackers.
Battery life is unreal - I collect every available metric every 5 minutes 24 hours a day, consult it dozens a times each day, have the screen on full-time during all workouts, and it still lasts a week+ between charges.
I scanned all my grocery-store, gym, etc. membership cards into the app and now I don't have to carry any of them with me - they are all on my wrist.
It has made a huge difference in my fitness efforts due to the motivation that comes from being able to precisely track what you accomplish.
There are some small issues that I would like to see improved: The app features annoying adds for add-on services (like more detailed sleep analysis) that require subscriptions. You can't turn them off either - they just come right back. It also includes an app store where you can buy watch faces and apps for a few dollars each. This is frustrating because almost all of them are available to download free from miwatchfaces(dot)com - they are reselling other people's free work and charging for it. My only other gripe is that the only Heart Rate Variability measurement function is a metric called "stress" with an arbitrary number that is provided after every measurement. This makes it difficult to interpret for one of the most useful ways of using HRV which is identifying when you are coming down sick a few days before you actually get symptoms.
Also, why does that app consume so much background data???
But don't get me wrong, there are very few purchases I have made this year that have been as positively impactful and valuable. This is a great watch.

Excelente
bateria dura mas de 10 días lo que me parece muy bueno que Samsung y apple son de cargar diario. La faja no me duro mucho en un partido de futbol se reventó así que recomiendo tener de repuesto. no pesa mucho lo que es bueno para usar par dormir y cumple con las funciones basicas.

Las diferentes mascaras disponibles están muy padres.
Buena resolución, buen peso, la pantalla es grande pero no incómoda , los materiales son de buena calidad cierto toque elegante y moderno.
Puedes ver notificaciones de tu celular, no puedes contestar llamadas , pero si rechazarlas.
Alexa incluido , solo que responde a comandos en inglés.
Se puede escuchar musica .
En la app puedes configurar muchos complementos como calculadora, reloj mundial, mascaras, modos de entrenamiento, notas , clima, calendario lunar, etc.
Se puede ver los resultados completos de reportes de estrés , sueño, ritmo cardíaco, PAI, oxígeno en sangre. Las mediciones son buenas y cuando mides algo en particular te da tips para poder hacer una medición más precisa.
Los modos de entrenamiento son muy amplios y con buenas mediciones.
La pila dura en uso constante más de 5 días y en uso normal casi dos semanas.
Viene con su cargador con cable usb.
El tiempo de entrega fue justo como lo prometieron.
Por el precio y lo que tiene vale la pena probarlo usarlo y sacarle más jugo , aunque si ya es tu segundo o tercer smartwatch probablemente optes por algo en otro nivel y por ende más caro acordé a tus necesidades que van surgiendo.
