What about me, I’ve always recommend to choose paid vpns only, First of all, they provide the higher level of security and performance. Secondly, subscribing for paid service you will be free from importunate ads. As for a definite vpn service, you should define the aim for using it. If you want to bypass some geo-restrictions, you should use this one, but if your aim is to be protected from being hacked, you should use another one. Of course, the choice depends on you, but I recommend turning on the number of servers and their locations, the connection speed, the type of encryption, the users’ feedback. As for me, I’ve use purevpn for a long time and haven’t faced any problems (https://www.bestvpnrating.com/service/purevpn). Actually I use it to watch Netflix and it really workes. Besides, the speed is great and impressive.
