It is ok. I am not keen on freefall when I cant see when i am falling so am not very keen but I would ride it again.
I went to the pin event on the 22nd and it was open for 1hr for the people at the event. Some of our friends rode it 6 times in the hour so it must be ok. If you get the chance to ride in the dark I would reccomend it as the view when they open the lift doors is great
