I'm a person who only needs a vpn very occasionally, and cannot afford the luxury of a top-of the line vpn. With Covid plus a broken cable to where I live, I have had problems even accessing news in my home country and downloading new drivers for my old laptop.
I was sceptical to see an offer of a free vpn, those I read about were all very flaky on privacy and were often usually slow according to real reviews.
Hoxx'a offer is genuine, you dn't have to pay, though they do advertise an upgrade 3 times faster and more connexions when you pull down the menu to connect. That is fair, and the cost just for a browser is modest.

Speed has been decent, I got 0 MB/s for some nvidia drivers on my theoretically 6MB/s connexion (it is 6 MB/s if you download from the ISP (!) ). Without Hoxx it was impossible to download a 500Mbyte driver. It would have been maybe 1 day to get just one.

But with Hoxx I got 1.5 MB/s, which is pretty damn good. It took 10 minutes for each driver with their browser add-on!

If your needs are simple, iike mine, then I'd recommend Hoxx with no hesitation.

P.S, They also do software to vpn all the connections from your PC as well if you need that. But I was quite happy with the simple browser add-on.
