I have one version of the Banjo Brothers grocery panniers. They are nice, but there are two issues. You can't use them in the rain (a non-issue probably since who wants to go grocery shopping in the rain), and, because of their rectangle shape, there can be a heel strike issue. Regular panniers have a non-rectangular shape so the heel misses the bag, but the grocery panniers are shaped like a grocery bag so they enter into the heel-travel area. It's not a bit deal for me because the grocery store is not far from home.
