Summary: First time I used my first XP it filled with water and I KNOW it was locked. Returned it for a new one and was sent the old one refurbished however the first time I used it bubbles came out all the orffices. Returned it and got a third camera. It has been updated and the locks are different. It works but I was without a camera for 10 months.
Pros: Nice size for underwater photography, Easy to recharge the battery
Pros: Has some cool features. Can take two pics at once, one with flash and one without to see which is better. It takes some pretty good pictures and underwater video was good.
Cons: Terrible battery life. Bought 3 cameras and just over one year later, all 3 batteries have crapped out. They all just stopped taking a charge. The batteries are expensive to replace. The underwater pictures didn't work very well either.
Summary: First off, if I could give this camera zero stars I would. We got this camera as a wedding present to be used on our honeymoon in the Dominican Republic. Luckily we packed two cameras, this camera only lasted about an hour. We took it out in the ocean, was under water only about 1 foot and afterwards camera read "card error" and we lost all photos on the memory card. Also water had seeped into the battery compartment and under the flash.
Cons: Terrible underwater pics, even after tweaks from the manual. Returned and bought Canon D10, worth every penny, amazing underwater pics and options. Don't waste your time or money with this camera. The Canon is worth the extra $.
