    Awesome watch

    Reviewed in the United States on July 7, 2025

    Color: BlackVerified Purchase

    This watch is awesome. Great style. Comes with two watch bands a metal link band and a soft rubber band. I opted to put the metal band on as my previous watch which only came with a soft rubber band broke although it would be an easy fix with a new pin I dont think it was counting my steps. This one seems to show that I've walked more than I believe I have. The features are awesome and you can change the face through the app on your phone.. a couple down sides is the charger card doesn't seem to hold on as strong as I'd like when I put it on the charging pads if I move the watch slightly it will pop off. 2nd down side there isn't a low battery warning like an audio beep or even a vibration to bring your attention to it but you can see the battery strength through the app. Buy how often would one look at the app to see the battery level. Still 5 stars as I should paid more attention to the battery level through the app. For the price point you can't go wrong why spend 200 or more for a watch when this one suits me just fine and it'll suit you too.

    It is amazing in quality. I would recommend it to anyone who needs a smart watch that is value for money, high grade. It syncs seamlessly with my phone and the accuracy and ease of use are unparalleled.

    It was decent for a while. The blood pressure was not very accurate but everything seemed to be. I did not like the band so I replaced it but after about 9 months the watch quit working completely. I did have the battery replaced but that did not make a difference. The audio on the watch was not very good but I really didnt expect it to be. Not sure id recommend this watch. It has nice options just didnt last as long as I expected it to.

    Its OK, increased to 4 star after some use

    Color: Black SiliconeVerified Purchase

    Overall i like it, not as sensitive as a fitness tracker, you can track your days vitals through the app, need to turn on elevated heart rate monitor and automatic health monitor i cannot find the info on the watch but through the app you can see your days heart rate and steps per hour, blood pressure seems low vs a doctors office, im usally 130/80 this says 101/66, maybe its because im not at the doctors to elevate my blood pressure?

    Its definitely a big watch, i have already cracked a gorilla screen protector, no damage to the actual watch. So i recommend getting a set of them.

    At first battery life was about 3 days, i turned off the raise to wake and it now last 2 weeks. The screen only turn on when i press a side button, touching the screen does nothing. I prefer battery life over the screen turning on when i lift my arm.

    Its pretty durable as im fairly active at work, steps seem to be 50% of what a Fitbit logs

    You cannot adjust the sensitivity to step force, casual walking around the house it sometimes does not log steps

    It does not log flights of stairs. Overall it looks good I think, easy to use, app is pretty simple, privacy seems to be ok as you can restrict what it has access to

    I don't allow location, contacts, and have most push options restricted, it sometimes tells who is calling, does not display texts, probably because of the restrictions

    Belle surprise

    Reviewed in France on August 25, 2024

    Verified Purchase

    J'ai longtemps hésiter à acheter une montre sportive à bas prix, mais les montres de marques sont hors de prix.
    Mais heureuse surprise. Cette montre semble de bonne qualité. Boitier en métal avec le fond en plastique, le verre répond bien au doigt, les couleurs et les graphismes sont agréables.

    Elle est livrée avec :

    2 bracelet un en caoutchouc et l'autre en métal.
    1 outil pour ajuster les maillons (assez simple à utiliser)
    1 câble de recharge (pas de chargeur mais il est possible d'utiliser un chargeur ou son PC)
    1 notice en français (mais succincte)
    1 carte de garantie international

    Elle permet de mesurer en continue ou à la demande :

    La fréquence cardiaque plutôt proche (testé avec un tensiomètre électronique)
    La pression sanguine plutôt proche (testé avec un tensiomètre électronique)
    Le taux d'oxygène dans le sang (pas testé)
    La qualité du sommeil (je dors mal et le résultat est proche du ressenti de ma nuit).

    Le nombre de pas, la distance parcourue et les calories (plus ou moins précis mais aucun podomètre ne donne
    les mêmes valeurs proche de celui sur mon téléphone sauf pour les calories elle est plutôt généreuse)
    Testé uniquement pour la marche.

    Possibilité de suivre de nombreux sport (testé uniquement pour la marche)

    L'application dédiée est plutôt sympas elle permet :

    De suivre et enregistrer les résultats en continu sous forme de graphismes interactif
    De suivre et enregistrer les entrainements (marche ….)
    d'effectuer certain réglage pour la montre notamment :
    le temps d'éclairage
    l'enregistrement en continue (le calibrage de certaine fonctions comme le pression sanguine).
    Et d'autre.

    Elle permet de télécharger d'autre fond d'écran (je conseil un fond d’écran avec indication de la charge batterie)

    Attention certaine fonction de la montre ne sont réglable que depuis l'application.

    Cette montre a une autonomie de 6 à 10 jours en fonction de son utilisation

    Attention comme pour toutes les batteries il ne faut pas descendre en dessous des 5 % car il y a un risque
    d'inversion de polarité et dans se cas la montre ne pourra plus être rechargée. Par sécurité je déconseille
    de descendre en dessous de 20 %

    Bref je suis satisfais de cette montre.

    It's a No Brainer. This watch punches way above its weight and I won't be buying "designer" again.

    Reviewed in the United Kingdom on February 1, 2024

    Verified Purchase

    Having used quite expensive "designer" smart watches for the last few years and suffered the woes of failing battery life with three successive ones. So I decided to give this a punt when my last one started to falter. I was tired of paying hundreds of pounds for something that would not last. I am seriously so impressed with how well this looks and functions. The steel bracelet is good looking/decent quality and came with the tool to remove links if needed. The bracelet feels every bit as robust as what I was used to and it even included a resin strap if I had preferred that. Wearing 24/7 the battery lasts 3-4 days before needing topped up which does not take long to do. The watch offers a few faces to choose from but I haven't investigated if I could add others. In any case I quite like at least half of the ones on offer and it is not guilty of having any cheesy styles often popular in products from further afield in the world. The display is crisp and surprisingly bright and has a torch function, which works quite well by turning the entire display area to bright white. The sensitivity of the display on when moved function is spot on. It has been connecting seamlessly to my phone with the android FitCloudPro app. In the app I have tried out the blood pressure, heart rate and oxygen measures. I have the proper devices for taking these and the watch is pretty accurate in all three. The sleep monitor is not bad, but not detailed enough to highlight any patterns of disturbed sleep.
    I can genuinely say I am most pleased with this after over a month of use and would recommend you give it a try.

    Great Watch. Good Build and Clear bright display

    Reviewed in the United Kingdom on December 8, 2023

    Really nice watch and build. Screen is clear and bright. The watch is easy to set up and simple to use. There are plenty of watch faces to choose from and also 4 different menu choices.

    I was worried at first because all my calls and media were playing the sound through the watch instead of my phone but this is easy to turn off. From the watch face scroll down then press on the phone icon and you can turn this feature off.

    Notifications work fine and you can add other notifications like WhatsApp, Facebook, Twitter, Instagram and messenger etc

    I think this watch is definitely value for money.
