JM , My sample was crystal clear inside the head and lens both. I tied mine off in the pond down where I do most of my testing for 7 1/2 hours and brought it back to the house and took apart what I could of the light and NO sign of moisture anywhere. The Lens / Bezels were all I could not get loose , but I looked very closely and no moisture as I say. My control ring also does not seem to be like yours as it is kind of stiff but moves fairly smoothly , it can be moved with the thumb but takes a little effort to do it that way and IS easier to use the control ring with 2 hands (1 hand holding handle). As far as the Anodizing mine looks to be “good” (not perfect but good) I did note in my video review about the SHARP edges on the lanyard holes also , as I felt the same as you in that they would cut a string attached lanyard.
My review HERE if you are interested in seeing the water submersion (or anything else for that matter) The light going into water (pond) starts at 5:30 of the video , coming out of water at 6:54 and the Teardown and still beamshots (couple of comparison shots with S70 also) immediately following that.
Note the teardown was done about 5 minutes after the light came out of the pond , as soon a I walked in the house with it.
