Well since I know own the D3 housing that says a lot about what I think of Aquatica. They make an honestly priced first rate piece of kit that withstands all the knocks I end up giving my cameras. A few controls had to be adjusted but this was usually the case a few years ago. Mine completed around 1000 dives before I upgraded and is now still going strong with its new owner.
My second Aquatica housing, the D2x is more refined and much easier to set up. This is a heavy rugged case which is a definite plus if you do a lot of diving. Further Aquatica has all but the esoteric accessories. A great photographic tool made better if you add the AquaView.
