Best DATAI feature but no warning of high mobile data usage. Hella slow speeds. Bad IPs with high fraud score (ipscore, scamalytics). Good DNS Adblocking.
5 devices for 5$ sucks. Account ID very unsecure can easily be passed around without your knowledge so don't share your Account ID with anyone. Mobile app buggy.
Nice Payment Options ( Monero, Cash, Litecoin).
Got supposedly raided with no data compromised.
