    Yes (2) Color: Blue
    Great watch, (almost) everything works, stunning battery
    Review after 2 weeks of usage.
    + great battery life. With notifications on, heart rate monitor on, sleep monitor on and screen brightness set to 50% worked full 10 days when low battery (15%) alarm showed up.
    + nice bezel and very comfortable strap
    + super smooth and fast between screens
    + nice and quite precise heart rate
    + good (enough) audio quality while calling through watch
    + quality/price ratio

    - not every notification works (for example SMS/text message does not work). Maybe it is matter of an App, not the watch itself
    - setting screen britghtness sometimes does not work. after screen is turned of it resets to 25%.
    - You cannot adjust in-call volume. When you decrease volume on your phone, watch still works in a full volume and it cause some speaker crackling.

    - It does not show contact name in notfication/call, only number, even when you manually add it in App.
    - only 15 watch faces, where some of them are weird and not readable colour-shiny pictures

    It's been two months since I got this gadget and I'm extremely satisfied. It exceeded my expectations. It also has drawbacks, but at this price, it's worth it.
    - First of all it is very elegant and well finished.
    - The battery lasts unexpectedly, over 15 days of normal daily use.
    - It connects quickly to the phone and you can really talk to it.
    - Nice app, easy to use.
    - Good display, full active.
    - The faces are a bit childish, too colorful and no others can be added (in this ver. of app, but maybe in a future update).
    - It does not read the phone's address book, instead the watch uses its own address book in which no more than 15 names (numbers) can be entered. Still enough for me.
    - Do not take messages from e-mail, only Calls, SMS, WhatsApp, Instagram, Facebook, etc.
    - If answering is activated but you want to answer the phone, not the watch, you have to wait 5-6 seconds after answering until you can start talk.

    Yes (0) Color: Blue
    It is exactly what it says it is
    I waited and waited and then waited some more before I received it but when the watch arrived, I was amazed at the features. I did not expect a $50 watch to work the way this one did. I can make and receive BT calls with amazing quality. My brother who has an iWatch6 could not believe that he spent $700 to have a watch with a few extra features than this one. HR monitor may not be accurate but Corn WB05 does whatever another smart watch priced 4 to 15 times more can do. Battery life is so good that I forgot where I put the charger because you don’t need it often. It has a lot of user-friendly features (too many to explain here). How do folks at Corn make an inexpensive watch with BT call capability, fitness features, Amoled screen and great battery life? It is beyond me.

    Valido prodotto
    Prodotto valido. Schermo AMOLED con buona visibilità anche sotto la luce diretta del sole. Buona qualità audio in entrata e uscita durante le chiamate e per l'ascolto di musica direttamente dall'altoparlante dell'orologio. Unico problema riscontrato inizialmente è la disconnessione bluetooth senza alcun motivo, nonostante tutte le autorizzazioni concesse. Altra pecca è la non visualizzazione, nelle notifiche WhatsApp, della dicitura "messaggio vocale" o "foto" (RISOLVETE); inoltre i dati del sonno e quelli della misurazione battiti non si sincronizzano con l'app wiiwatch2 (RISOLVETE).

    Muito bom
    Smartwatch muito bom. Bateria excelente, usando a três dias com brilho no máximo, bluetooth ligado e está com mais de 80% de capacidade.
    Tela AMOLED muito boa.
    Alto falante excelente.

    O que não me agradou foram as interfaces. Contudo excelente compra pelo preço apresentado.
    Obs: Produto não foi taxado, porém foi necessário pagar uma taxa de despacho de R$ 15,00.

  • What are the benefits of AMOLED screens?

    Compared with ordinary watch screens, AMOLED has the advantages of high color contrast, rich colors, quality, and superior raw materials, just like the difference between 4K and 1080P TV glass.
  • What are the advantages of dual bluetooth modules compared to single bluetooth modules of ordinary watches?

    Dual-mode devices support Bluetooth BR/EDR and BLE, which have more power storage, more stable links, and a wider range of link devices than a single Bluetooth module.

    In dual-mode devices, these two technologies use the same RF front end and antenna. Typical dual-mode devices are smart phones, tablets, PCs and Gateway. These devices can receive data sent via BLE or Bluetooth BR/EDR devices, and these devices often have sufficient power supply capabilities.

    The power consumption of a dual-mode device communicating with a BLE device is lower than that of a dual-mode device communicating with a Bluetooth BR/EDR device. The dual-mode solution requires an external processor to be sufficient to implement the Bluetooth protocol stack.
  • What can I do about waterproofing?

    WB05 supports ordinary life waterproof. It can prevent sweat or rain from splashing and meet daily water needs. Since it has speakers and microphones on its body, it does not support bathing and swimming.
  • What is the purpose of higher resolution?

    Like a TV monitor, the higher the resolution of the watch, the more delicate the screen display. The resolution of 390*390 is better than that of the ordinary 240*240 resolution watch screen, and the vision is more vivid.
  • Can I receive and reply / talk directly from this watch?

    It has speaker and microphone functions, which can support talk to receive and reply directly from this watch.
  • Is the entire display panel touchable or only a dedicated area?

    Full touch, the entire display panel is the touch area.
  • Can the watch display interface be changed?

    Yes, you can directly change the dial on the watch. There are 15 beautiful original dials built in the watch. You can also download more dials or customize the dial background through the APP.
  • Can its strap be replaced?

    Yes, you can buy a 20MM width watchband for replacement. The design of this watchband is ergonomic. You can easily replace more watchbands with a spring buckle.
  • What is the name of the application?

    WiiWatch2, an App with stable connection and downloading more watch faces.
  • What can I do about music control?

    It can control the music playing software that comes with the mobile phone system, and it can play music directly from the watch without playing music through the mobile phone.
  • Can I use this watch to make calls or edit text messages?

    It supports making and receiving calls. You cannot edit information. Please use your mobile phone to operate.
  • Why can't the device start or start normally?

    Before using it for the first time, please charge the new device for at least 10 minutes or more to ensure normal startup of the device and optimal operation.
  • How can I choose the smartwatch that fits me the most?

    You can consider these points:

    ● OS & compatibility

    ● display material

    ● buttons or touch

    ● APP and features
