Android Smart Watch I6 Mens Watch 2GB+16GB MTK6580 Quad Core 3G Wifi Heart Rate Watch Phone With GPS+Nano SIM Card

good smart watch but the battery only lasts the day if you don't use any of the features. The strap is awful quality too, so change it as soon as you can.

Poor

Most SIM watches worked for me 6 - 9 months, this one stopped working after 4 months.At the beginning button not always responded, later battery started to heat during charge (which suggests watch charging controller is faulty) and eventually it stopped.

The watch seems to be a small android phone, allowing you to download all of your favourite applications from the play store - Netflix, google play, Spotify, angry birds, etc.The main compromises compared to a phone that you would put into your pocket is the screen size and the battery life.Although you can (just about) use applications, the battery percentage drops fast - I have measured a drop of about 10% per 30 seconds when using netflix or google play for example - so you will not get much further past the opening credits before the watch turns off (presuming you were at 100% charge when you started) - and it gets hot! Even Spotify is not much better.Even if you don’t use the phone, the battery will drop quite fast. I have not yet got more than about 6 hours out of it, so make sure you have a spare alternative watch (and phone) with you.I am not quite sure on the ‘sweet spot’ for this watch. Does it save you from taking your phone with you - possibly, but only for a short outing. Does it replace your watch? Again, not for long. You will probably need to bring a phone with you as well, for telling the time and doing any real activity rather than showing off what your phone can do - for a few minutes.I would agree with previous reviews around the strap (get a different one) - and the battery life.Very interesting device, however, have learnt not to count on it.P.SI have turned off certain feature to save battery life. Before this, the battery was dead before lunch time. So it’s worth taking at look at what you can deactivate.

it can both connect the wifi and use SIM card 3G internet, watch movies and download apps . it can make phone calls and send messages ,also has fitness tracker function. the watch face is changable ,really love it !

Been using this for few days .it's a great all rounder for tracking steps, running and fitness activities and sleeps as well , and you can view your messages , calls, heart rate and Notification from your phone.The app is easy to use once the date is sync from your phone.. Brilliant buy especially for the price.worth buying .

This Android Wear watch is amazing! It helps with my daily work life by giving me all my emails whilst on the go. I can listen to my music through whilst working for hours on end. The quality and style of the watch is breathtaking and i honestly wear it more than any other watch.
