It’s not lifetime 30GB. It one year 30GB.
It says “lifetime 30GB-per-month license”.
However, there are a couple of big negatives immediately obvious:
1. Very few of the VPN location options are available on this plan – most cannot be selected. A major limitation they did not bother to mention.
2. It immediately tries to modify your “hosts” file without permission. That’s a no-no.
I also noted a bug right way. It won’t minimize to the tray. It just remains invisibly active when you close it.
