To the developer of Tunnel Bear, I am asking for a refund of the year's subscription I purchased a week ago. I tested it under the free 500MB trial after 2 years using BTGuard. TB was perfectly stable then. I was impressed by the simplicity of the interface, appreciated the wit, and was pleased by the wide selection of servers in many countries. Once I had a paid subscription, TB first refused to download bit torrents until I discovered this could be overcome by activating the TCP override option. Then I started having infuriating problems with connection stability, disconnecting and reconnecting on average every five minutes and showing notices that it was having trouble creating secure tunnels. Un-clicking TCP override or changing other of the minimal options had no effect on this problem. If TB worked, it would be one of the best utilities of its kind, but as it is unusable (for me), I can only give it a half-star for effortless installation. If it doesn't work, it is more than useless, it is an annoyance and best and perilous at worst! A pity I now have to uninstall it and may lose the money I paid for the subscription!
