Well, the whole thing took 5 minutes and it wasn't bad at all! I guess I'm lucky not to have started needing them till the advent of modern equipment. I've certainly heard lots of horror stories!
One very nice touch is that they provide aerosol deodorant in each changing room -- bad for the environment, good for the people I have to be around the rest of the day! LOL I felt bad for stinking out the tech, though.
