    The packaging used by Amazon was really good.
    Coming to the packaging of the watch itself, wow, the unboxing experience was comparable to that of APPLE products, really clean.
    And coming to the sensors, it has Heart rate and SpO2 sensors along with a 6 axis accelerometer.
    1. The Heart rate sensor works fines with a margin of error of 2-3 beats per min.
    2. The SpO2 sensor is not a gimmick, it works fine but not 100% accurate, it was of by nearly 2% every time.
    ** Both the sensors do no work if the watch is not on your hand**
    So both are just not for namesake and are functional.
    **It doesn’t have GPS built-in the only CON at this price.
    **The display is pretty good and gets adequately bright.
    Coming to the battery charging time, it takes around 1.5hrs for 30-100%.

    ***Update 1: The battery only lasts for 6 days, when HR set for continuous for every 10min, sleep tracking on and also notifications on for sedentary and calls and exercise tracking for 30 min a day.

    Checking SpO2 10 times a day manually and always on for stress measurement.

    Lifting the watch up to light the screen for nearly 50 times a day.
    I expected it to last for atleast 7 days though(claimed was 9 days).
    ***UPDATE 2: Using it for nearly 2 weeks now , received a firmware upgrade, and the accuracy of the SpO2 as well as the HR sensor have improved and also the battery life has improved to around 7 days now.

    ****UPDATE-3( 24th Jan 2021): Using it for almost 3 months now, I guess all the hugs ar fixed, most of the measruu are accurate, but the step counter sometimes registers steps even if I don’t walk :P.
    Battery life on average 7 days with HR every 10 min and stress measurement on and daily once O2 measurement and sleep tracking.
    The band is pretty comfortable, no skin irritation or discomfort.
    Received around 6-7 updates till now.

    This watch is a good budget choice based on my usage for almost 3 months now.

     Entrega muito antes do previsto e produto muito bem embalado e em perfeito estado.
    Amei o fato de ser delicado e ficar perfeito no meu braço (que é fino e os relógios sempre ficam largos, mal ajustados).
    Iniciei os testes nas configurações e até agora tudo funciona bem.

    Update after 3 months usage:

    -Sleep tracker has gone drunk from past few days. As you can see in the photo, I slept at 1:31 in night and woke up at 8:29 in morning (which are correct records, kudos for this) which means I slept for 7 hours but it’s showing just 3:30 hrs. I mean it’s simple maths. Lol.

    -After disabling all trackings, I’m getting more than 10 days of runtime out of this(screenshot attached). Which is sufficient I guess. With all trackings on, you can get 5-7 days.

    -It had many small bugs when I purchased it, like spelling errors, not been able to turn off heart tracking, but in the recent software update they fixed aome of them, though the accuracy is same as it was, 70-85%.
    So yeah they might also fix this sleep tracking bug in the next update.

    -Also, get a screenguard for this since the screen is not fully scrach-proof.

    It’s a good watch but there are a lot of things that could be improved. I’m using this watch for 3 days and this is what I found-

    -pomodoro timer is effective for any focus work. I use this while reading.
    -have a lot of exercise modes. Though I don’t really use them.
    -alarm is effective. Always get me up.
    -can control songs and camera from this. Good feature.
    -magnetic charger is good and easy to connect

    -Unable to turn off full day heart rate tracking. It turns on automatically.
    -a lot of spelling mistakes.
    -steps counter is about 80-85% accurate.
    -i tested heart rate while on my exercise bike and it showed only 70-75% accuracy.
    -charged this watch to 95% on the first day and it have 50% battery on the 3rd day with full usage. So battery could be improved.
    -when I lift my hand to see the time, it takes about 1 sec for the watch to light up. This can be a little frustrating if you’re in hurry.
    -i tested it’s spO2 and stress tracker as well but not sure about their accuracy. Though I believe it’ll also be about 70-85% accurate.
    -sleep tracker is also not intelligent. Like if u went to bed at 11 and used your phone or book for 1 hour and went to sleep at 12 then it’ll count your sleep from 11 and not 12.

    Though I’m sure some of these cons will be improved by the next software update.

    So if you want to buy this watch then go for it if your main purpose isn’t heart rate tracking or other tracking and just want a smartwatch for alarm, timer, and other little stuff.

     Lightweight and compact.
    Decent accuracy. I tested it for a short time and step tracking is very accurate. SpO2 is a bonus and it seem to be working well (I can’t comment on the accuracy, but it does show different readings for different people and measures successfully only if you wear the watch tightly. So it’s not a gimmick). I haven’t used it long enough to comment on battery life but it should be good enough. Display is good and has decent resolution and good brightness. It could’ve had less bezels and more display, but it’s not really a big deal at this price. Interface is fast enough. I didn’t have any problem with it. Vibration is strong and you can change the intensity of vibration. The magnetic charger pin is convenient.
    It doesn’t have always on display feature which is not really a big problem. But if you want that, you should buy another watch. Build quality is not great. It’s decent, but nothing special. It feels a bit plasticky. Go for it at a price of 3500. But I don’t think it’s worth buying if price is more than that because it doesn’t have GPS, AMOLED display, premium materials.

    Update : Battery life is 4-5 days with continuous heart rate monitoring(I set it to every 5 minutes) and sleep monitoring(It increases heart rate measurement frequency automatically when sleep is detected) on. So it’s good enough. It’ll last a week if you don’t wear it during sleep for monitoring (I only did it to test it and it works well. But I don’t think I’ll wear it regularly during sleep).

    Comprei com as Lojas Fenix aqui na Amazon e o relógio apresentou defeito na primeira semana. As vezes não media o oxigênio e nunca media o estresse. Ele possui uma função muito boa de avisar, numa atividade física, o limite máximo e mínimo que vc colocar de bpms, porém esse relógio não media certo, uma hora avisava num limite muito alto e outros mais baixos, nunca o correto, variando muito. Pedi a troca e hoje recebi o mesmo relógio, na mesma embalagem sem lacre (o relógio ainda veio com um arranhão na parte superior). Achei uma falta de respeito da loja, pois paguei por um produto que dizem ser ótimo e até agora não pude aproveitar. Vou ter que cancelar o pedido, infelizmente.

    Voltando aqui um pouco depois pra dar um retorno: a loja Fenix fez o cancelamento do meu pedido certinho.
