I used their free trial, £15 cashback through quidco at the minute. Wasnt 93 days though.
I thought they were fab re sending out dvds/great turnaround times, but a bit tricky to cancel. Was over a year ago, but I do remember having to make 4 phonecalls to get it sorted (and refunded when they charged me)
I got a lot of exercise dvds to try out and any I liked, I bought off ebay. Also good for dvds you think you will only watch once.
