I have a 5l Topeak Tourguide as well. Lots of pockets and dividers No problems with it on two different 5 day gravel tours so far. One quirk and this may apply to other handlebar bags that sit high on a drop bar as well but there is no where to put a headlight. It comes with a extension bar to mount stuff but it's not high enough for a light to go over the bag and anything rigged up to the bag itself flops around to much. My work around on an as needed basis was a small light and a rubber band on my helmet. Great for occasional long dark tunnels and such but not riding at night. I only had it in two days of rain but it stayed dry with the included cover. I did spray the bag and cover with Silicon Water-Guard repleant as a precaution. I can't say if that helped or not. Amazon warehouse occasionally has them "used" cheaper. Mine appeared to be brand new
