Works well on my Fire TV stick, location Germany works fast and is not yet blocked.

However, the apps, whether Fire stick or Windows or browser, are extremely rudimentary. You can set or influence virtually nothing compared to other VPN services. There are also very few server locations, e.g. I really miss Hungary/Budapest.

I'm not sure whether OysterVPN will ever be able to catch up with the competition in the foreseeable future and develop into a fully-fledged service.

Postscript, addressed to AppSumo: I really wish that there would be a lifetime deal for a really well-functioning VPN service again, and not just those that barely work, soon disappear again, or have other major restrictions.
