Same as @snoons@lemmy.ca. Got my remaining mullvad time refunded and switched to iVPN for a month to test and then reupped.
No complaints so far. I use it on a couple Linux machines and Android. I tested it out on my router and it worked but I haven't had any cause to use it at that level yet.
You'll get the rare slowdown or reconnect, but I've run into that with any VPN I've ever used. They're once in a blue moon though.
*Edit one very minor complaint I remembered is that left clicking the tray icon in KDE does nothing. You have to right click > Show iVPN. I rarely have to use it, but it was annoying at first.
