The harness fits well and secures the camera well. However, it doesn't have quite enough range of motion to keep the camera facing forward when seated on a bike. The result is you get great video of the ground, but not enough of the horizon. Need to add an extra link between the camera and mount to improve the range of motion.
Just got back from a week trip with the Overhead Rolling 2600. It met all expectations. Bigger than some "22" carry-ons and enough pockets to keep stuff organized without being cluttered. Wheels, handles, zippers, and materials all functioned well. Only checked it for half of the flights so it didn't see tons of abuse. Solid product.
