I've been out a couple of times now with my new "Take-a-Look"mirror which is mounted on my sun glasses. There is a learning curve for this thing, but I think it is going to be just fine. I found I kind of needed to do a drop left shoulder, raise and turn head slightly to get the best view from it. The hard part was figuring out how to adjust it right on the glasses. It also has a mount for ny helmet that has to be glued on. I hate to try it on the helmet then not like it there and be left with sticky stuff on my new helmet. Certainly it is better than no mirror for me and my self confidence on the road.
