I know they have a loyal following, but I was very unimpressed with the Rosen visors in my J. Particularly for the J, perhaps, the visor goes into a pivot that is only a screw into the plane's frame. If I swung the visor forward, the screw tightened. If I swung the visor aft, the screw loosened. I was constantly getting bonked by a swinging visor on takeoff. I always had to have a screwdriver up front to tighten the screw after each use. I contacted Rosen to be sure there was not a missing part. I even sent the visors in to be confirmed they were the right parts. (I do applaud their custome service). It really needs a bearing or a Teflon bushing with some friction adjustment, so the screw is not torqued when you swing the visor. Note that the Mooney factory visor used the same mounting point, but the swing was in a bushing part and never torqued the mounting screw.
Other issue is if you have the compass on the post instead of glare shield. The visor will hit the compass. So you must move it in all axes with every swing from stored position to sun blocking position.
With my Ovation, I decided to just carry sunglasses rather than get another Rosen set. I think Muncy's are the right balance, based on the pics. Not too big, so they will not hit the compass.
