I wouldn't even put one star to be honest. When we tried it once there was nothing said that its a subscription, we did one off payment on a credit card about 3 years ago ( well we thought that it is one off payment) and since then money was been regularly taken out every month and they were not shy to take out payment twice in one month! When we rung them to ask for refund they just politely told you where you can go! So much of their 30 day money back guarantee! Beware and avoid!
