Opinions of Mullvad as a standalone VPN?
The first thing is to ask yourself: - Why do you want a VPN? - What do you expect from a VPN? Personally I don't like them, they don't protect you from anything, they simply serve for example to evade the denouncements of certain governments for p2p downloads or to be able to visit websites that are blocked in your country, they are not useful for offering privacy. Any “legal” company is bound by the laws of the Fiat system, it cannot protect you. If you want privacy Tor or i2p.
