When I had Mulkvad my speed test would go from about 335mbit to like 327mbit when connected to a somewhat close server.

Connected to servers across the ocean it’d be like 310.

They got a money-back guarantee if you don’t pay with something completely anonymous like cash in the mail.

I just did a speedtest over wifi and got 530 down / 260 up with 45ms ping. I connected to a server a few states away and also got about the same with the closest server. I do have gigabit fiber though

Never ran a speedtest. Fast enough
