I use them on my utility/commuting bike and like them a lot. Yes they are noisy and it takes a little work to get them on but they beat the heck out of panniers for sheer convenience. I can fold them up and clip them closed when I don't need them and they are always there. They bolt on so its harder to steal them. I got a couple of recyclable grocery bags for 99 cents each that I put in them to carry whatever. The bags are cheap and fit close to perfect. Put a couple of bungee cords across the top when they are folded up and it quiets them down nicely. I have loaded them up with groceries, beverages, camping firewood, picnics, and they handle it all. I would buy them again.
