If for some reason the tunnel is lost, it does not warn you, does not have a "kill switch" or some way to stop traffic, nothing. So you could be at that expensive coffee shop, with this product on, go to amazon (that doesn't work cuz amazon hates VPN traffic), and use your credit card, thinking you are safe, but you didn't notice a tiny flag changed and your info stolen. You thought you were safe, and not a flash, not a beep from your speakers. This is a serious security flaw.
