$15 per month for VPN that is not good for netflix probably due to low speed is unimaginably on a high side.
Let me explain my pricing.
For Netflix you should use DNS-proxy which is only $8 per month. It does not encrypt/decrypt your Netflix traffic thus is faster. You actually do not need encryption to watch Netflix because there ain't sensitive data there.
For secure browsing (bank sites, e-commerce) you should use VPN. It is slower, but secure and costs also $8 per month.
All servers are operating fast because they're not excessively loaded with connections. The latter happens with a lot of people who buy DNS-proxy and VPNs from regular providers.
