Am having huge problems and bloody Speedo are useless - their email adress is on the website stating that they will help you with any technical issues but they just ignore emails and you can ring Speedo direct but they don;pt put you through to the department they will just pass on a message and they don't call you back either!
Am really cross was £70 and haven't been able to use it at all - I was going to be a size 4 (yeah right) from all the swimming I was going to do whilst listening to music!
