Sorry to hear some of you are having problems with the slider on the bracelet. Mine is ok so far - it does move slightly, but not enough for me to be concerned about it yet. I will keep wearing it to make sure it does not get worse. You would think that the slider would have been tried and tested to make sure problems did not occur - very annoying when you really like something, and have to return it due to a fault - which will then just be marked down as 'returned' on your account!
Mine has been ok so far too. I did wear it again over the weekend and it was fine but noticed at work on Monday that by the time I got home the slider had slightly moved, but only a tiny bit.
If I did end up having to send mine back I would ask for a replacement, as it's faulty not unwanted and see if the next one is as bad.
