Premiumize is a shadow of its former self
Sadly, Premiumize is no longer the service it once was. The elimination of a number of North American servers has reduced the quality of service for many clients, resulting in slower speeds and more buffering when streaming. Its additional “features” have also become far less reliable. What used to be the best service for me is now behind competitors. No matter which server I choose, I get buffering. Two years ago, when there were more server choice, I never experienced buffering when I chose the fastest servers (all of which are now gone). Your money is better spent elsewhere.
