I have just had the second olympus mju tough fail me in the water. The first camera was replaced free under warranty, the second has just failed due to water ingress. Once they stop working outside warranty - that's it - on to the scrap heap with £200 of camera.
Fantastic looking watch . Forget it if you want it to tell the time. Very dissapointed . After one repair in USA which was costly to send (even under guarantee) the watch still fails miserably in delivering its primary function.
