What are the inside dimensions?

I would say useable inside space is 6" X 3" X 1" - especially if you intend to use it for a larger cell phone. The top of the storage area is larger than the bottom, hence the other dimensions in the other answers. I like my cell phone to sit flat on the bottom and not at an angle.

If this fell in the water with about a pound of weight in it would it float

I just tested it for You. I put at least a pound worth of stuff in it , which filled it almost completely. About 1/4 of the box remained above water. I hope this helps You.

Is it fully submergible?

Someone gave me a used one with the clamp missing off the long side of the box. I put a piece of toilet paper inside and then submerged the box in a bucket of water. Figured i better check it out before trusting it to protect my phone on the river. Checking every 15 - 20 minutes, I noticed no water inside till around the hour and fifteen minute mark. Even then, it was just a little.

Has anyone tested its durability? Such as dropping it from an extreme height?

I bought about 15 for my white water rafting guides to use in their trips to carry their phones. So far so good. The case has stood up to lots of abuse. As for dropping from height I wouldn't worry about the case but would be worried about any fragile things inside the case as it is not padded on the inside. Hope this answers your question
