'Subals ND2H, mine is one of the pre-ND2 housings, has been fantastic.The controlsfeel as accurate now as when I bought it from Ocean Optics in London. I never soak the housing in fresh water, preferring just a quick dip in the sweet-stuff after dives. This is not an ideal strategy and is based on my personal paranoia, which comes from seeing too many cameras flood in the rinse tank. However, there is no corrosion on the housing. I have seen much newer housings from other brands look much older. I am still using the original o-rings in the housing and on all the ports. The faded strap on the handle is the main give-away to the workload. The base of the housing is a bit scratched and the rubber feet are a little worn down, mainly from dragging the housing into the water when shore diving'
