These scammers hide a notice that "you will be billed $19.95 a month to keep your service going" (something to that effect). I only found out about this when the charges hit my paypal account the second time (I disputed them with paypal - hopefully they'll reverse them). Finding and cancelling the auto-renewal is about as difficult as curing cancer... it takes a whole lot of digging and clicking through multiple levels of menu to get there. Avoid this service like the plague.
