I like the look, but for me, they do not work as well. There seems to be a trick to getting them positioned, which when you figure it out, helps quite a bit, but I still do not think they are as functinal as the stock mirrors.
Performance machine makes a nice replacement for the fairing mounted mirrors. they offer them in chrome polished and black. they are pricey but look great. They might be a little bigger than the stock street glide style mirrors.
Recently installed a set on my 01' Ultra. Once you get used to looking down and seeing your hands in the mirrors. One big plus is less wind noise without the old mirror stems flapping in the breeze. I think it's just takes a week or two to get used to them.
