We use this VPN at work and although I was not a part of the initial set up process as a user I find it very well developed.
No bugs or lags thus far (on mac and ios) and I can give a huge thumbs up to their online blog (cybersec nerds will appreciate it). Keep it up guys!
I have been using this app for over a month now during the quarantine. Slick design, easy to manage and use, quick and stable connections throughout. Truly a good service.
