    Excelente equipo, la pantalla tiene muy buen brillo y las características como el medidor de oxigenación de sangre es genial, la correa ajusta de forma correcta y sin aflojarse, puedes manejar la música de tu celular mediante la pulsera, si buscas un medidor de pasos , ritmo cardíaco y oxigenación de sangre esto es lo mejor que encontrarás por este precio, la sincronización con el celular es mediante su aplicación zeep y está puede enlazarse con tu cuenta de Google Fit para guardar tus datos, vengo de una mi band 5 de Xiaomi y es lo mismo con el plus del oxímetro.

    Bateria do relógio dura bem, coloquei ele pra monitorar batimentos e sono direto, brilho em cerca de 50% por cento, durante o dia 100%, gastou pouca bateria em 01 dia de uso, utilizando cronômetro e etc. Pulseira muito confortável, material muito bom (observação para o excelente detalhe que prende a pulseira que sobra, com uma trava pra ela não correr o risco de soltar).
    Relógio leve, mas robusto, material parece super resistente. Touch com ótima sensibilidade, botões super funcionais.

    I have to write this review because I was misled by a lot of negative reviews and waited for long time. I almost decided to buy the Fitbit verse 3, but wanted to give this band a try first.

    I have owned two Samsung smartwatches, one Fitbit, and a new Apple watch 6 for wife, but I am looking for a simple, light, long battery life particularly with Alexa control function smart device. I finally made decision to try it. It took less than 5 minutes to setup EVERYTHING. The screen is beautiful, super crisp text. The Alexa function works perfectly even without the ability of speaker. I can read text message, and get phone call notification. It has a lot of basic health fitness tracker features that are very useful. I would give it 5+ stars.

    Now, why I disagree with some of the negative reviews which is misleading.
    ** Simply the most important: set the right/realistic expectation for a $35 smart device that can do Alexa control
    1. Not accurate: come on… is the xx steps difference really that important for you which will destroy your whole health tracking plan? If yes, go spend $400 to get an Apple watch. what’s important is the trending: did you exercise consistently, do you have a surge or drop in the heart rate suddenly.
    2. Buggy software: I set it up and forget about it. I am not really sure what buggy is about. Are you doing a stress testing for a $35 device?
    3. if you are pulling out each feature and compare with a dedicated device or apple watch or Samsung watch, why don’t you buy all those devices to make sure you are happy with everything?

    Last comment/warning: the screen is small, the text may be too small for some users. For me, it is really trivial comparing with what I am expecting from this smart Alexa band.

    Thanks.

    Es un buen reloj Smart muy parecido a la mi band, funciona idéntico solo que aquí usas la app de ZEPP pero tiene las mismas funcionalidades, tiene medidor de estrés y de oxígeno adicional a las funciones de medidor de ritmo cardíaco que manejaba, muy práctico, la pantalla tiene mejor calidad de imagen

    Lo recomiendo bastante

    El producto está bien pero no es lo que ofrecen. Amazon sería bueno que corrijan la publicación del producto. Es la Amazfit 5, no la 6.

    I bought the T-Rex to use as an everyday watch, instead of using my Garmin 945, which requires charging daily at my current activity level and when using it as a music player. Obviously, I did not expect the $140 T-Rex to measure up to the $600 Garmin, but I could not resist seeing how it would stack up. I used the indoor cycling for my spinning class, outdoor running for my running group runs, and walking for my fitness walks with my wife. For spinning neither the Garmin or the T-Rex integrate with the bike, so about all you get is duration and estimated calories. For running the Garmin offers fully customizable screens, but with the T-Rex you get what the app is set to display, but with distance, pace (min/mi), heart rate, and most important, auto-pause, I think it would fit the needs of most runners. The walking app on the T-Rex Compares to the Garmin, much as the running app, with one oddity, which make no sense to me, as the T-Rex shows the walking pace in MPH. As far as, GPS comparison, on 12-mile runs and 7-mile walks, the variation, in the Garmin and the T-Rex, was within .03 miles, so not too shabby. The T-Rex does offer an always on display, but you must choose between a pointer screen or a digital (See Photos). Then you can elect to enable the raise your arm feature to show you actual screen choice. I understand the power save feature, but I would like the option to use my screen choice for my always-on display. With SMS messages you get a notification and tapping the notification shows the sender but doesn’t allow you to preview the message. For phone calls you get a notification, as well, so don’t expect iPhone functionality. The AOD (Always On Display) and AB (Auto Brightness) are separate features, but the T-Rex lacks the important always enabled AB, during activities. When the activity occurs in non-daylight hours the always enabled AB feature is not that noticeable, but in daylight the screen is not readable until the AB kicks in, which is very annoying. Your AB and screen choice can be set to activate when you raise your arm, but there an irritating delay, even when set to the arm raise’s sensitive setting. The soft rubber band is comfortable, but I did notice while grilling, that it picked up the smoke smell from the wood chips, which was removed with a good bit of scrubbing with a scented detergent, odd but worth mentioning. With 2 hours of activity, requiring AOD and GPS, I can easily get 4 days between charges and when using it without activities, I would expect well over a week. Amazfit has obviously focused on battery life, but in my opinion, as an activity tracker, athletes will prefer to have screen feature choices for the AOD and AB, knowing that they sacrifice battery life. The internal storage will notify you when you need to sync the activity history to your phone with the Amazfit App, so there is limited storage. The music app will control the music player on your phone, but you must restart the music controller app on the watch after each change, so I find it virtually useless. Remember to install the Amazfit App on your phone before attempting to setup the watch, the app is required for the initial setup. In summary, the Amazfit T-Rex is an excellent value and a decent activity tracker, with the potential to become great activity tracker, with a few software modifications. I have received no products or compensation for my review. I am simply trying to answer the questions that I had when considering the Amazfit T-Rex and hope it proves helpful. Also, hope to see it back in stock soon.

    Antes de falar do produto, preciso começar agradecendo a Amazon e o vendedor. Recebi em menos de 24 horas, não deu nem tempo de ficar ansioso hahah.
    O relógio é maravilhoso, É um pouquinho grande, e pode desagradar algumas pessoas, mas achei bem bacana! Os sensores são bem precisos, comparei os batimentos dele com um oximetro e tive pouquíssimas variações. O gps sincroniza bem rápido (porém o do celular ainda é mais rápido nesse quesito) e os dados dele são bem próximos aos do Strava, sendo ainda mais fiel em algums momentos, pois quem usa o Strava, sabe que ele dá umas velocidades máximas absurdas haha. Existe uma boa gama de exercícios monitorados, inclusive uma para os treinos ‘funcionais’ na sacada durante a pandemia. A bateria é bem satisfatória, mas isso é relativo ao uso. Deixo a tela desligada, e não tenho muitas notificações ativas. A durabilidade e resistência são o ‘fator principal’ nesse relógio, uma vez que em termos de software é basicamente a mesma coisa que o GTS/GTR, porém isso só posso avaliar com o tempo. Estou extremamente satisfeito com essa compra. Só não gostei muito das watchfaces disponíveis, mas é só fuçar um pouco que vc acha algo do seu agrado na internet.

    Got my T-REX via Amazon (pre-order) yesterday. I’ve had a G shock for daily wear and looking forward to testing the durability of the T-REX. It’s not as heavy as the G shock.

    Instructions kind of rely on your previous technical experience. No other instructions than some basic phone-to-watch pairing. My experience was:

    unboxed
    tried on my wrist (very much like the strap is soft silicone with a tab inside the band holder to keep the extra from coming out)
    connected charger (magnet is good, but not very strong)

    9:55am
    BT pairing
    GPS update
    resource library update
    firmware update
    syncing
    10:01am

    Charged to 100% before wearing it.

    So far I have turned on auto heart rate and sleep detection, alerts for all apps I use, turned off always on display. I have been changing the watch faces and playing with the settings. I am at 89% battery since yesterday morning. Not sure if the battery life will improve as I get used to and aren’t playing with it constantly. I want to take it on a hike soon to test out the ‘workout’ functions. I didn’t get it as an apple watch alternative. So, I’m not expecting it to be as smooth as an IOS device. For what I want, I think the T-REX with work.

    Feb 28, 2020 UPDATE: 10 days of heavy use, max brightness during the day, continuous heart and sleep tracking, notifications for most apps, use of alarms… this morning my battery was down to 10%.
    SO, I got 10 days without a recharge. The cool thing I like was that the watch was fully charged in about 40 minutes.
