I've got this same bag and it's great. I like the two side pockets that I put my phone and billfold in. It comes off easily and I take it off whenever I leave the bike. The only thing wrong is it wobbles a bit. Also, now that I've used it for awhile, I've gotten used to it and would like a bigger one. I'll be going with a rando type bag with a small rack. Probably too big for what you want.
