Z11 Pulsera Inteligente Presión Arterial Monitor de Ritmo Cardíaco Rastreador de Ejercicios Bluetooth Pulsera IP68 Impermeable Deporte Smartband

Good smartband for the price.
Good sincronization with the phone.
Looks nice and is confortable to wear.
Can be used as a watch even without the phone just fine but you do need the phone for the initial sincronization (I use it this way because of the annoying train-horn sound the app makes when the bluetooth signal is interrupted).
Functions work fine.

Sugerencia

The app is simple but fine but it emitts this really annoying train sound each time the bracelet disconnects from the phone, which happens quite often and randomlly. So until this issue is updated in the next version of the app, forget taking this to a meeting or such.
Battery lasts about 4 days, even without having it connected with the phone, but the battery itself is quite irregular and you never are sure when it will turn off.
If the bracelet turns off, after charging it needs the phone to sincronize the date and time.
You use the wrist to activate the backlight but this rarelly works as intended, sometimes not lighting even with intense movements or just randomly turning on (and remaing on!) with static.
The vibration of this bracelet is quite wierd, as you can sometimes hear something within the smartwatch rumbling. I am not sure if my unit is somehow damaged or something just came loose inside.

The material of bracelet is very comfortable and the combination of colors is very attractive. I wear it all day and compare both the daily number of steps and the quality of sleep. It is great to measure not only the pulse but also the blood pressure or saturation of oxygen in the blood. It's a shame to have only two hands, I'd buy another one now :-) This smart bracelet is excellent, now i have 3 pieces in my family and as a gift for my friends.

It is great as a smart watch.I bought this instead of a bulky expensive fitness tracker, the style is very elegant and It is a dainty more feminine fitness tracker / smart watch, as long as you download the Smart Wristband app ， It's actually really easy to set up, then I find many features ： such as find your phone, which is a cool job
