A few months ago I purchased a Fujifilm Finepix XP150 underwater camera. I specifically bought this camera so I could use it on my kayak and a little bit of snorkelling. Now this thing is supposed to be waterproof to 5m and they recommend not using it for more than 2 hours underwater. That's all fine, I followed all the instructions, rinsed it off with fresh water, didn't open doors while wet, blah, blah. And it was never in the water for more than 30 minutes and I only dived down a max of 2m.
After the first 3 uses, it started playing up. Opened the door to find the terminals corroding inside so it had obviously been leaking. So I decided not to use it in the water anymore, but it stopped working all together in the end.
What P's me off the most is I purchased this (well it was a birthday present) specifically for a holiday and this was ruined by me not being able to get photos and videos out on the water as planned. It has now been 6 weeks since it went in for repair and still no word and quick search of the interwebs resulted in stories of other people with the exact same problems as me.
Rant over. Ahhh that's better.
