There’s more too it than that, but if you're using the PIA client software, it generally handles kill switch functionality and prevents DNS leaks. You’ll find wireguard generally gives better performance than OpenVPN. The no part is remembering that it needs to be on to work and if you turn it off, its staying off. Some retailers and indeed sites don't like VPN’s, expect to be flagged for fraud/additional checks occasionally, or some things just wont work. Theres a healthy debate about PIA’s ownership being questionable as the parent company has some pretty nasty history and they hired the ex owner of Mt. Gox for the group of companies security, this is a man who claims he was too dumb to secure coin wallets properly or notice that millions was stollen, so possibly not the most obvious choice. That said zero documented cases of PIA providing logs to 3rd parties and its basically free via Quidco etc. so on that basis it could be a lot worse.
