I have had 3 Olympus Stylus models. And have had problems with seals in 2 of them. ("They" do say you need to have the seal maintained annually, neither of these either made it to a year.) I got them at LLBean outlet, so they replaced them. I have to say I'd have been hesitant to buy them otherwise.
Underwater photos and videos are good, as are outdoor pictures in good light. Indoor photos with flash leave something to be desired. (Ok, not horrible, but I'm used to a DSLR.)
