Impossible for me to verify their no logging claims, but Mullvad have worked well for me in the past, and you can pay in cash using a randomly generated numerical user ID, which strictly limits what they directly know about you. The fact that they accept these payments, and that Mozilla work them with them for Mozilla VPN and presumably have done at least _some_ due diligence, give me some level of confidence that they are sincere about their other claims.
