Anyone do primarily kettlebell workouts?

Options
I did my intro class today to teach me the basics and I have my first real class Monday. I am really excited and nervous at the same time. The place also incorporates ropes and... I don't know the correct term but straps that hang from the ceiling with loops at the end to do all kinds of workouts. So it isn't 100% kettlebell but about 90% or so. Just curious if anyone else does a lot of kettlebell classes/workouts and if so, what is your routine and results? Thanks!
