Smarty DNS used to be a very reliable choice but now the servers don’t work properly and customer support is basically absent or extremely slow in replying. Often they don’t offer a solution which is a pity.
It has not been possible to connect or use the smart DNS service for several days. Support is never online and support tickets are not answered. Looks like they are still taking new signups, this is surely illegal.
Speed is absolutely slowed down to a crawl on VPN, geo-tricking doesn't work reliably on Netflix or Hulu, and their business practice on so called "lifetime" subscription for writing a review (they told the internet community when they launched that you could get a lifetime subscription if writing a positive review) is very, very shady. They give free subscriptions for writing a positive review on their service which would not be necessary if their service help up to standard.
