Question: How do you access the camera's controls?
Document: Cant be beat for the price. Works well with camera's controls. Used it when I went wade fishing and it was in the water the whole time with no issues.
Bought this to take photos at the beach. I was very skeptical at first, then impressed that it didn't leak when I first tested it, and even more impressed when I found how easy it was to use my camera's controls while it was inside the box. I mostly use a Canon Powershot for fun, everyday photos and it fit perfectly inside using one of the included foam strips.
I BOUGHT THIS ITEM RECENTLY AND WHEN i bought it says that works with cibertshot w320 , but  it doesnt work , the camara is to small you can not Access  all Camera Key Controls And Features
This will fit many different digital camera's, the buttons seem to be easy to push, just changing the setting takes a bit more effort. It is water tight and felt my camera would be safe in it. My only problem is with my Sony Cyber shot you can not use the flash because where the box is made for the lens to come out is also where my flash is so all it does is glare.
Use this for our point and shot (Sony DSC-WX10) and have been pleased. It is a basic, water-proof case and we have found good value despite some of the limitations. It's quite hard to operate the camera functions (like zoom) but ok to press the shutter button. Have to put some muscle into opening and closing the case. The camera's flash cannot be used.
Underwater is ok, I guess, but you can't really even see what you're taking a picture of and it comes out so dark (my camera's fault though, not the case). We've been using it for snorkeling, but it just hasn't really served its purpose. Our pictures taken up above the water look like crap because of the water all over the front plastic piece. We should have just bought a waterproof camera. I still give it 4 stars though because we haven't had any water leaking in.
Did a great job keeping the camera dry while we took many, many pictures at Atlantis Resort Bahamas. There are three points that made this waterproof case less than perfect (one of which is my camera's fault) and cumulatively cost it only one star.1. Since this is a one-size-fits-lots kind of case, it comes with two foam blocks to act as shims in order to keep a camera stationary inside.
I bought this for my Coolpics camera and at first was skeptical but decided to give it a try. Went snorkeling in Jamaica and the housing worked as advertized. Granted I didn't test the depth noted but for my snorkling pics it worked great. Was able to operate most of the camera's features when it was in the housing. The only feature I couldnt operate was the zoom feature but other than that I would recommend this housing for the underwater pictures your interested in taking with out haveing to buy a new camera
It was a little hard to turn on and turn off and use various controls, but for the price, I feel that it was a good purchase.
I was able to get some great video with this thing. Also, cameras with touch-screen controls can be a little problematic as well.
Answer: the clear plastic part of the case is some what flexible.  You can use "push" buttons but if you need to "turn" anything you are going to be out of luck.  all I did was turn the camera on and off and push the shutter button so I didn't have a problem.
