I am one of the very few that did not like them.
I was able to purchase a used set, and put them on the bike shortly before I left on a trip. I did take them for a short test run before the trip, and immediately noticed that I did not like them. I thought, well they are new, and I need to give them a real test. I left them on for a weekend ride of about 1600 miles, and as soon as I got home I took them off. I just didn't like the leg position of them, I felt uncomfortable the entire time they were on. Just in case anyone is curious I am 6'05" and do have highway pegs on the bike.
I am not trying to get into a debate or say they are bad. I know I am in a small minority, or maybe the only one, that didn't care for them.
