2 years user here; purchased the Tier1 way back in 2023
Had some patchy moments with no connection at times but overall it was there when I needed 99% of the time.
Not that many server location or features, just the basics for quick and easy coverage.
I haven't seen much development over that time;
Some implementation of port forwarding and/or Wireguard protocol would have been nice as it seem to become more common among the industry,
But at least no benefits were lost; I feel I'm still getting the same value as I did 2 years ago, which seem already a big W for a lifetime deal.
Overall still stoked about the product and would warmly recommend!
