Well I tried my Mirrors for Sevens mirror at the Se7ens gathering in Roaring River, Mo., last week, and it was GREAT!!!! I found myself not even using my two outside mirrors after a while. Very stable and it even worked when I put my top on. Very well made product. I recommend it highly. Just be sure your windscreen frame is 14mm or 9/16" thick. My extrusion was 5/8" thick and I had to mill it down for the clips to work. But no big deal. Russ
