I was worried about how small they are. The do need to be adjusted perfectly to get the full range of viewing, but the convex mirror makes this possible. They don't get bumped like larger ones so they stay adjusted better. There are tightening screws to adjust how tight the adjustment stays. They don't stick out the side of the fairing so they are protected. Very good looking on the bike (Street Glide). Lots of comments on how nice they are and I really like them.
