I know we had issues with ours, although one issue was due to really dumb actions by one kid. Ours was GoForth if I remember correctly and it had 3 towers, anchored of course in ground with cement for both trailers. Right after the inspection at one of our larger fairs a kid got on it, bounced the seat and over went one tower and kid fell to ground. He lived as grass lot but I think he broke his leg and battered.
Second time a tower went over show owner dropped it right away and sold to a show in Mexico I think, but we didn't stake towers like Strates did, should have that would have stopped towers from going over I assume.
I rode Strates model and always enjoyed, his was a bit higher than ours and really his looked better.
