Buoyancy - Neutral. Balance - Excellent. Includes - Housing, flat port, all controls, microphone. Controls are easy to reach from the handles and easy to use with the thickest gloves. The camera tray is another nice bit of design.
All cables run from the tray, which makes electrical connections to the housing when it is docked.
But the Alpha is fully upgradeable. This is the Alpha with a clear acrylic front face and an even lower price. Miss - Buttons hard to push with heavy gloves, no safeties on latches. For - Most Sony TR and TRV and Canon ES cameras. Controls - Electronic, all functions.
