I have used seedit4me 'Sidekick Pro Plan' for almost 2 weeks. And I can say this is great! Creating an account is so easy, their dashboard is simple but awesome, seedbox setup is also so easy. And their help-support is great too. Their staffs are so smart and skilled. I haven't experienced any crash with the seedbox. Speed is also awesome. If someone wants to buy a seedbox then I recommend seedit4me. At least you can try the Sidekick plan for a trial.
Thanks, seedit4me for these kinds of services and @Ethan for giving me the opportunity to use such a wonderful seedbox.
