This is a nice case that fits the camera perfectly. Nearly all controls are able to be used when in the case and the flash diffuser is easy to snap into place. This thing went down to 100 ft. with no problem. it's rated for 130 ft. My only gripe is that you need to purchase separate case weights and trust me you need them. It should also come with some silicone grease for the seals.
The product is well built and sturdy. However the reviews particularly in CNet were correct it does have its limitations. For instance once inside the camera it does not allow for access to the options turn dial. Also I found that the lense would water camera would fog up after 30 mins of use.
