I've been using SmartDNS for 6 or 7 years now and it is a brilliant service. Works nearly all the time and on the rare occasions some service stops working, customer support is excellent and they'll get you back working again quickly. Only thing lacking is a VPN app that works on a Firestick but you can still load a free OpenVPN client and use the SmartDNS openvpn profiles, just a bit more effort required.
