    CACGO K2 Smartwatch per iOS Android Smartphone NERO
    Cacgo K2 Fitness Watch
    This watch is very nicely built and seems solid, it is responsive with a beautiful clear display that has levels of brightness to choose from.The straps are rubber and the main body is metal, the face is not so big that it devours your wrists and it can accessorize with many suits and dresses.
    The watch is packed full of features including 3 different sport modes and it is also waterproof (according to advertising) it also has heart rate monitoring and blood o2 levels and more you can find in the listing.
    Now for some honesty , the straps are held in by retractable pins which seem sturdy but it feels like it cannot be used for those who do rougher and more manual activities without them coming out.
    Another downer sadly is the wrist motion sensor to get the face to light up when you turn your wrist doesnt always respond the way you want it to or at all (but for the price its a minor quality of life frustration)

    Great Smartwatch!
    Great item. It has a crisp, clear, bright display (but not VERY bright in sunlight) and good battery life. I was impressed that after my first charge it lasted about 12 days, then (i don't know why) when it was around 30% it turned off. Probably the measurement is not very accurate. But it's more than i expected and i'm very satisfied with the battery life.
    The app is good, at first i had syncing problems but after the app update it works smoothly.
    Sometimes the watch changes state on it's own, i'm not sure if i touch it by mistake or not, but the clock display (it has 3 modes) has to be pressed for 3-4 seconds to change state and that's hard to do by mistake. It's not a problem though.
    The strap is very nice, soft and doesn't bother me at all even when i strap it tightly.
    Tested it under water (shower) no problems yet. I've been using it for 20 days now.

    Overall, i'm really satisfied with the smartwatch.

    Awesome watch
    I have have purchased this watch and I satisfied with the product and it's upto the word that is said in the features. Initially I was worried what if the watch is fake and it's features are false but when I got the watch in had and I was equally satisfied... the features are good clear screen and the sleep count function is awesome as it calculates your deep and light sleep. even the time when u went to sleep and wake up from sleep. but the only problem is that the watch sometimes doesn't lights up itself when I raise my hand to see the time or activities.other than this issue the watch is fantastic.
    The gear best app, I have one request to you guyzz plzzz provide the tracking and courier company name and phone number to the customer so that they can call and enquire the status of the product

    Smartwatch K2 ótimo custo Benefício
    Deu essa qualificação pelo seu ótimo custo benefício, um smartwatch com funções básicas mas importantes, ou seja, as que você mais vai utilizar. o K2 possui mostrador de horas, pedômetro, função esportes, verifca batimentos cardíacos, pressão sanguínea, oxigenação sanguínea, alarme e monitoramento do sono, e notificação de apps, ou seja o básico de um smartwatch mascote principal. o K2 é aprova d'água, muito bom para quem pratica natação e quer monitorar seu coração. com a pulseira em silicone torna seu uso confortável e não incomoda durante a noite para dormir podendo assim fazer um monitoramento do seu sono sem desconforto. Smartwatch K2 eu recomendo para quem quiser comprar.
    Algumas melhorias que acho necessário; melhorar o Bluetooth que desconecta com facilidade, a função girar para visualizar tem que ser melhor calibrada e poderia ter GPS, mas pelo valor é um ótimo custo benefício.

    Nice watch, but very inaccurate
    This watch is ok for its price, it has a long batterylife (already 2 weeks without reload and still 50% battery) but ist functions are very inaccurate. tested heartrate, the watch states 70 bpm, but in fact it is 50 bpm, bloodpressure is 7 - 9, while it is 11 - 13 on a reliable device. also stepcounter states a lot more steps than a reliable stepcounter.

    So If you want a nice watch with a good battery life and you don't care about the inaccurate heartbeat, bloodpressure and stepcounter, but just as a watch buy it, if you want reliable data about the heartbeat and so on, save you money for an other watch. Strats 2 for instance.
