I have/had the trek interchange. I really like it. But, operator error (me) has caused me to have only one pannier left. My trunk rack bounced off one early morning because (I assume) I didn't click it in correctly. This was at 4:30am and by 5am, theives were already using my charge cards. Then, on my first commute this year, I again (I know this to be the case) didn't click my bag on correctly and was going down a hill, hit a pothole and the bag bounced off. I didn't know I lost it and a guy in a truck caught up to me and told me. It got lodged under another vehicle and all but destroyed.
That being said, I really liked these bags. I have/had them for 3 years and they were/are (the one pannier bag left) is very handy, has a built in rain cover and clicks on/off easy.
Operator errorwas my downfall, but I have to admit, they are nice.

) Besides the wear issues that I mentioned earlier, it occurred to me after I posted that there's a strong possibility of cracking the stays if the clamps are overtightened or if the rack is overloaded, creating a stress on the stay in a direction it wasn't meant to be stressed. Never mind that carbon stays are often not round, which would mean extra stress on the contact points for the clamps, as well as extra places for grit to get in and wear. 
. Is there any other risk that you have heard of other than it wearing the post over time?
with me, even though I truly love the forum, it can wait a day or two for me to return
