I went to AirVPN a few months ago after my Proton was expiring because I needed a VPN with port forwarding. They do a sale every anniversary (somewhre in Spring) and maybe one or two during winter holiday times.

It works like a dream in my homelab (gluetun + qbittorrent) and the Linux GUI client works, although i think you have to keep the app open while using it...

On Android, it's been jank. Like at first, it worked without issue and was great. But within the past few weeks, sites won't load, I'll have to refresh it often, and just general issues. This is happening both on my Graphene Pixel and my stock Galaxy Tablet. I think the Fire TV works well enough.

I did a speed test when I first got it, and for my laptop it only seemed to decrease by a little.

I was considering IP Vanish before I picked Air for the price.
