Ooooh, ooooh, ME!
I gots one and use it for my 4255 Garmin. Works bitchin', man! When I crashed the box took a hit and is a bit wonky but all I replaced was the flexible face piece.
I did make a sun shield of of piece of rubber sheet from OSH Hardware. Attached it with some Velcro.
Not a bad price, very sturdy and the face shield lets me have touch control with the gloves on. All around good thing!
