I have the Bumot luggage (sides and top) installed.
All of the kit, to my eyes is top notch quality - everything aligns, everything feels extremely solid, and mounts well. I also have the Bumot bash plate, and this bombproof quality extends out to that as well. The boxes have friction hinges which is nice, as they stop where you leave them.
I've ridden with them through pouring rain, and no leaks. There are some nice options to them as well. For example, the racks can be ordered with an integrated matching keyset toolbox. The boxes have tie down points for extra stuff to be strapped to them. Inside the lids there is a strapping point to keep stuff stuck on the lids and to use that space.
For the pics - ignore the vstrom - that's the wifes.
