The WG-AS1 water guard is useful for protecting the camera's hot shoe contact when the SB-910 or SB-900 is mounted on the D3 or D3X

Lets me use the flash, SB900 without worry of getting the hotshoe contacts wet when out shooting in the rain. Keeps water run off from the flash from contact with hotshoe contacts. Great accessory.
Extra support on the flash hotshot, also protects from water damage
Keeps light rain, moisture and dust out. Can stay on flash shoe to also protect from bumps when the flash is not mounted. Does not seem to snap even though there are catches on each side for it, but still stays on fine and pretty much seals.
