I rode one of these at Linnanmäki, Finland quite a few years ago. That was a ride I'll probably never forget. The ride's not located in the amusement park any longer but I watch videos of it on RU-vid every now and then. It truly was the craziest ride of my life, I've never felt quite so dizzy than I did when I got off. Super Waltzer at the funfair comes kinda close, though. At least my head handled that one better and I was able to ride it a few times with only a few minutes in between of each ride.
