It was incredibly difficult to hear the instructor over the music most of the time; unless one knew the routine, it was hard to follow. There were few suggested water breaks in the schedule, which isn't great. What really turned me off, though, was the admissions lady's attitude. I got lectured about causing the instructor to lose money by using a discount voucher as though I was doing it maliciously. I had been planning to pay for a year's worth of classes after my discount month expired, but I won't any more.
