Tried the New York, Canada, Mexico, Germany, and Argentina servers. Both in single and multihop configuration. Have it installed on both iOS and Android devices, and previously had it on my OpenWRT router prior to ISP blocking it.
Used to get 300Mbps a while ago but then one day I woke up and barely got 20Mbps, maybe 30Mbps on a good day. Not to mention obfuscation rarely works these days anymore. Was a happy ivpn customer for 3 years until I wasn't, at which point I made the switch to proton, and now this.
EDIT: want to add I have always had a 1gig connection if it matters at all
