Their web systems and UI are clunky and still needs a lot of work. Server stability and patching process has improved. I have tried them three times in the last 4 years (Astroneer Server, Valheim Server, and Enshrouded Server).
Their credit and auto-renewal practices are near nefarious. They deliberately obfuscate how to adjust and save turning auto-renewal off. They will argue on policy and terms with you during cancellation to scrape an extra month of charges out of you and block a refund. Read everything carefully if you do choose to use them. Any charges as credit you will never get back. They will charge you for credit purchases over the total cost of the service, then leave the excess credit in the account which you cannot use or be refunded and they will just claim after 3 years of not using it. Better services offered from other companies with less deceptive or sleazy business practices.
I will never use them again. Go read up on their employee reviews if you are curious why they behave this way.
