The biggest complaint I've had in the past was the difficulty in cancellation of the membership. There have been times in the past when i leave the country and it was difficult to deal with their cancellation policies.
So I got the skinny right form the club. You just go in 10 days before the billing date and you will have those ten days plus the following month to use the membership. So you can effectively get a 2 month membership by signing up and canceling any time in the next 2 weeks or so.
I'm planning on using the club for 3 months. So I will do exactly as instructed and if all goes well, my review will not change.
