If you dare to use their 7 days supposedly free trial, then don't. They make it very difficult to cancel your membership and when you contact them on day 7 they tell you that your subscription has been renewed for 12 months but you can shorten it to 14 days and they still charge you for £7.99 for that...
There is no number to contact them only by email and of course you don't receive a response on time to cancel during the free trial!... be warned!
