I have found the Sea and Sea housing for my D7100 to be a very solid and fully functional piece of equipment. It is easy to operate and I am able to access all the functions of the camera easily. It accepts many ports which are easy to change out. I was a Nauticam user for many years and this was my first housing made by anyone else. I am very happy and satisfied with the switch and would recommend this housing to anyone thinking of using it.
