I just installed the Bestem 929, their biggest, onto my 2014 Suzuki Burgman. It went well. Just added a few washers above the back spacers to fill the gap. Once I ride for a few weeks, I will modify the tupperware to fit back into place. I have no opinion, other than the instructions are very general and skimpy. Most YouTube data is out of date and does not address specifics of the 2014. Bolts holes are not perfectly lined up, and came up with some extra pieces (a couple of brass looking channel rails about 12 inches long x 1.5 inches wide and some bolts). I am guessing this is a modification for another model. For the price, it will do for around town. The thickness of the walls of the case are obviously thin compared to much higher priced units. Since it is easily removable, I will only attach when I absolutely need it to cut down on sun exposure, which would make it brittle and weak.
