My wife has really been happy that I picked up a Corbin trunk. It makes riding so much more enjoyable for her. Now she's the one wanting to go on long trips. I also like the fact that everyone says I'm now MUCH more visible at night, and this replaced a GIVI E46 w/ light kit.
I have some concerns with it, also: I'm not sure about the long term durability of the finish. There are a few spider cracks underneath that can't be easily be seen, but I'm going to leave it off the bike as much as possible when it's not needed to avoid more of them. It's not hard to switch out, but definitely not something I'd want to do all the time; and you won't be hauling it into the hotel room at night. Also, I can feel the weight of it back there, even when empty. Like other Corbin products I've seen, the design is an acquired taste, and you just have to get used to the fact that some of your buddies will make fun of it. But then those same people will want you to carry stuff for them.
(In the picture I've attached, you can see that it looks right at home with the back end of a Boxster; my brother had just changed his meds, and was feeling dizzy on the day of our last ride, and drove the cage. Funny thing is, I have about as much cargo space as he does).
