I bought these bags about two months ago at an LBS after my pannier bit the dirt. I have been very happy with them so far, and even brought home a 12 pack and some groceries tonight with them. My only wish is that they had a shoulder strap. Often when I'm making several stops shopping, I don't like leaving my pack and goods on the bike. It would be nice to throw the whole thing over my shoulder to carry into the store with me. And for trips where I need more than a 12 pack, I zip tie a milk crate on top of the rack and I've got a spot for the bulky groceries and the smaller items go in the bags. I also use them for work, the change of clothes go in one side and lunch and coffee thermos in the other. But again, they just aren't well suited ergonomically for carrying off the bike.
