I bought a 7D and a Hugyfot 7D housing for it soon after. I love both.
My only one-time complaint with the housing was the following: I initially only had a 4GB memory card which meant only 10 minutes or so of 1080p footage or 200 RAW photos before an ungainly swapout was required. And, as other reviews have pointed out, changing either battery or memory cards in the Hugyfot require breaking down the housing entirely since the body is the first thing to go into the housing, separate from the lens, not to mention an additional 30 minutes of pressure-test waiting.
This was easily solved by upgrading the memory card. I chose to go with 32GB which now give me more video than my video light batteries can provide, so no more swapout is required and the LIMFAC is now on my light batteries which come in at around 50 minutes to power the dual 50-watt bulbs.
As for the housing itself, aside from being sexy, it's very compact and the layout is almost button-for-button the same as the camera itself, which allowed me to continue to give proper attention to the dive details and my team rather than towards any learning curve associated with a new housing.
