I have ten to fifteen yr old Ortliebs. Love em. Back Packer Plas, front Packer Plus and front roller. Used primarily for commuting, grocery and laundry runs. Now off road. Double hooks on the bottom and triple top hooks on the big back Packer. Especially like the quick flip lever top hook slide adjustment when moving the bags to different racks and bikes.
Only complaint are the fastek type clips where if you’re not attentive, in a hurry, frozen fingers etc and jan them together so that they aren’t lined up such that one tooth is outside the female clip it gets broken off. Then you’re left with a somewhat proprietary buckle to match or redo the whole buckle set up.
Speaking of bags, my other favorite frame bag, Revelate Tangle, has velcro straps that come apart in time requiring some repair. I think it might be UV damage. The top velcro strap ripped apart when removed as well as the two small velcro loop straps that attack to the head tube and down tube. The zipper is starting to fail. Have to remember to lube zippers.
