I use them nearly every time I ride, mostly commute to work. My karate leg swing is getting better and I've learned to keep a hand under my right knee to help it clear.
I think the weak point of the bags will be the zippers. It looks as though the hem's are already stretching a bit. I swear I see a slight purple hew in sunlight, like they're already fading. They also cause noticeable turbulence at hwy speeds.
Pros: They work, came with the bike and I actually like the way the bike looks when they're mounted. They also clean up really easy with a stiff brush or some mild detergent when really nasty. The sticky release issue is better with some work on the locking pawls, but not perfect.
I noted my skepticism with dealer at first service and they told me they would replace if not meeting standards for up to 2 years.
