Ok, so I've had this rack since August '09 (2.5 years) and I have had no problems with it. I've driven from NY-TX, TX-FL (2x!) and loads of 2-hr drives with my bikes. I'm 5'9 (and female) and I can haul my bikes on my roof of my SUV by myself- the side arm is really quick to put on and adjust quickly.
Popping the rack off and on my car is a breeze (after the first few attempts to get the hang of it). I do suggest getting a bike lock and locking your bike frame down to the roof rack as extra security. No bike rack is theft proof...(but I haven't had a problem yet)
It holds my hybrid, roadie, and 29'er hardtail perfectly!
Just got back from a 3-night camping trip with my new 23- it was fantastic! There were some heavy wind gusts (which sent my friends' tents flying) and the 23 stayed put.
Had to pack up rather quickly (wildfire threat). Easy to put up in the dark too.
