I am not expecting much on the quality side...
Dunno, Andy; sometimes those sorts of things last and last, despite all expectations. Or are "good enough" for the purpose and never get replaced 'cos for the money, they can't be beat! I've found such items grow to become favorites, and then I put way too much time and effort into repairing them years later 'cos by then they're Trusted Friends and I'd be lost without them! If it looks like this is headed that way, quickly grab another, as such things go off the market as soon as they become Favorites.
I like the idea of the "dual pannier" design; it allows for a choice of foodstuffs on either side. I'm guessing a person could even stuff a light wind jacket in one compartment. Looks like there's a top pouch made specially for a small phone and some mesh envelope side pockets as well. Can't go wrong with that for the price. It's made of nylon, and if the stitching ever lets loose, there's always SuperGlue. Should be fine.
These and similar little bags that ride atop the top tube and have a loop that goes 'eound the stem/steerer are increasingly popular with the bike path crowd I see passing my window daily. Same reasons, too -- they carry house keys, some billr or change, ID, 'phone, and some gel-food or a few dry snacks. Pretty hard to beat for that purpose. I hope this works well for you.
Looking forward to your review!
Best,
Dan.
