Been using this service and the app for 7 years. I've tried others (Nordvpn, IPVanish, most of the ones that are frequently in a Top Five list by reviewers). I come back to PIA because: 1) Apps for Windows, Mac, Android, iOS and Linux, along with browser extensions for Chrome, Firefox and Opera. Cross platform is important to me. 2) Variety, number and locations of servers, virtually all parts of the globe covered. 3) I get full bandwidth that my ISP offers even when connected. 4) No logging (of course this is matter of belief with any VPN). 5) RARELY any connection drops, and I'm on all the time. All my personal machines are on VPN from the time they boot up, 24/7. 6) ten connections per account, up from 5 last year. NordVPN only up to six. Many of the other 'top ten' are still only five devices. If you have a lot of devices, something to consider. 7) truly anonymous purchasing, you can use V/MC gift cards (bought with cash), and no billing address required (use a bogus address, tech support confirmed to me doesn't matter), can also accept store gift cards for Payment (Walmart, Amazon, Target, STarbucks, and so on)
There was a significant price hike this year, after being in the $35/year range for the longest. Now it is $70/year, but if you purchase two years in advance it is only $84 total for the 2 years, or $42/year, plus you get 3 months free, so it's 2yr and 3 months.
