Before rating it, I strongly believe that programs like this must be given for at least a week trial before paying for them, due to many negative feedback about such programs regarding them slowing the browsing and some times even failing to do what they claim to do. In my case now I need one of those but who guarantee that it will fulfill it’s duties !! Because once the price money is paid no way on earth can claim it back in case it does not function the way it should be.
