I am so glad to ave found this site, and although I am sorry for anyone who has suffered due to injury on the Ab Circle Pro, I am gratefull to have made this connection. I too injuried both my knees after the knee pad slipped out of the knee cup in the mid revolution. I was swung off the machine directly landind opn both knees on a hardwood floor. I have a wedged meniscus, but due to the fact I do not have insurance I have not been able to get treatment. I was wondering if there was a class action suit, and if not how can one be started? If anyone can help me please answer at this e-mail address: [email protected] read full review »
