Surfshark now has the Wireguard protocol available. It's much faster than OpenVPN protocol. iPlayer works very well with Surfshark in my experience. I've just changed from NordVPN to Surfshark. Never had any probs whatsoever with Nord over 3 years, but decided to give Surfshark a go, largely because it's cheaper. So far I think SS is very good. Does what I want it to, but at a cheaper price than Nord. As already stated by @Tofer above, SS is now part of NordVPN's portfolio.
