I bought this for £23 thinking its worth a go, and if it is really that bad then its destined for the bin.
Firstly i charged it for 3 hours then put it into the strap, a tight secure fit, (battery lasts 3 days without use and a day using quite a bit) Then I paired it with my s3 and downloaded the sony app (the web link is in the instructions). All connected and after setting up the facebook and email notification section, all works!. If you get a problem with the bluetooth dropping out then keep your finger on the right watch button until the media control pops up, start to play a song then pause it by pressing the right button again, this keeps an active connection open as its waiting for you to press the button to continue playing (mine stays connected all day this way),then keep your finger on the right button until you go back to the main menu. DONT ever press the left button, its supposed to instantly turn off the display but also tends to turn off the watch!(and you have to re-pair etc...) Note: when you pair/connect with bluetooth WAIT for a miniute before using he watch, give it time to sync before pressing any buttons or it will disconnect! (about a min).
NOW HOW TO REMOVE THE WATCH AND CHARGE: put the watch on a flat surface, put your fingers either side of the strap (where the pins are) with one hand each side, fingers on the top face of the strap, making sure your finger next to your thumb on each hand is over the full length of the pin (we dont want to bend the pin!) and butted right upto the body of the watch, put your thumbs under the watch in the centre, and push hard with your thumbs, the watch will literally pop out the strap carrier! as easy as that!
The bottom line is, this watch is a total give away at this price! get it before its gone!!!
