I agree. I have Ortlieb backroller classics, and I am just as impressed and have had a similar experience as you. They quickly and securely clip on and off of the racks on both of my bikes (different racks, but no problem), and they are totally waterproof and just about perfect in every way. Some bike items are spendy and you question whether it's worth it, but panniers for a regular commuter are one area you want to spend and get the best, for value you appreciate every commute day.
