Is the TracRac Pro easy to take on and off?

I was looking in to purchasing the TracRac Pro, and I was curious how easy/quick they are to get on and off. I'm looking to haul surfboards (longboards) on my 2006 Tacoma Double-Cab shortbed. I only get to go ever-so often, so I'm thinking that I'll want to leave the ladder rack off most of the time.

I looked in to the bed-extender route, but with a 9'0" board hanging out the back of the 5'0 shortbed, it just seems a little risky.

The TracRac pro seems like it will do the job nicely, but I was just curious if it was going to end up becoming a permanent fixture

 

from the looks of them they seem easy to take right off, just unscrew the knob and slide it out. maybe the base stays on the truck? I may get a set of these one day
