I'm using 4 VPN services. Below is my personal thought.
Kaspersky Secure Connection (my 1st one, fast enough and simple to use which is based on AnchorFree - Hotspot Shield. Not able to stream Netflix content)
NordVPN (got it for *free* through a Youtube channel). Glad I tried it before I subscribed for this service myself. Difficult to connect to a server (maybe 1 out of 20 tries) and it is very slow to connect. App usually logout for no reason and you have to re-enter login information). Can access to Netflix US and UK but not usable on Smart TV.
VPN Unlimited. Got this lifetime subscription for $15. Good enough to access to Netflix US.
TorGuard with Streaming bundle using 50% discount code. Found this one is really good and I love it so far. Have 2 streaming IPs so it is less likely to be blocked by Netflix. Support is very good too.
