I have the Corbin Beetle Bags and very happy with them. They look great. The fit and finish is awesome. They attach in three places, but I found it easier to just use 2. Once attached, the bags are like part of the bike. You forget they are there. A passenger can still sit comfortably, and they integrate with Corbin's rear seat and your grab rail, if used. When off the bike, the brackets are very small and unobtrussive compared to other products. I had my brackets chromed and they actually look good...a bonus. They come off in 2-3 minutes.
I just used them for my Laguna trip, and they worked great. I took them off when I reached the hotel and went back to the sleek style of the Busa.
However, they do have limitations.
1. They are small and will NOT hold a full face helmet. The curves for ergonomics, aerodynamics, and style, create lumps and humps that you have to get around to get larger objects in.
2. They attach with acorn nuts and thus are not quick release. However, with a ratchet, removal and attachment is relatively quick.
3. The acron nuts are accessed from inside, so if the bags are full, you can't remove them. Think about it. How do you get the bag of clothes into the hotel? Corbin did not intend for the bags to be removed frequently.
4. They do not have a carrying handle. Again, Corbin sort of planned the bags to be semi-permanent once installed.
So if you are out for looks, and are cool with rather small bags, the Corbin is a good choice. They are expensive ~$700 and delivery is something like 8 weeks.
Good luck.
