What a fantastic post. I do not completely yet understand, but I am resteeming this post, so besides sharing it, I'll have easy reference to it.
So, all VPNs would help secure my location when I visit websites, but paid VPNs will have better band width, little to no advertising, privacy, and customer service. That's the basics as I see it for now- but I'll read again. Thank you for your knowledge. The graphics are very apropos, and may I suggest referencing the author on those too.

Thank you for reading and your time. I asked my professor and he claimed that paid VPNs are prevailing over free VPNs. They provide much better service, and they are safer. He believes expressvpn is trustworthy and regarded as one of the best VPNs. https://pixabay.com/ and https://www.flickr.com/ are the websites I visit when I need free images.
