New mirrors, had fold down ones and didn't care for them. Left the "normal" ones and did a comparison to see if it changed what I could see behind me and I can actually see more with these. Gonna take a bit of adjustment to get used to looking down instead of over to check the mirrors. No more folding mirrors once I leave the pavement. Haven't had chance to get them up to speed to see what the vibrations are compared to stock. I do know that on some bikes the mirrors can cause unstable air near your head, time will tell with these. So far worth the $20 on fleabay.
