Anyone ever used one? I never carry much with me and don't have mounts for a real rack. They seem nice but I would love to have some input with hands on experience.

Hold enough stuff for a commute (the most I carry is a change of clothes and lunch).

Does it have a hard time maintaining its position? My clamp on rack that I use now likes to shift on me if I stand up to pedal or if I corner really hard.

Thanks!
