Slickvpn is a simple and effective VPN that's light in the pocket. I paid for a VPN the first time last year; Slick lived up to the hype of being one of the fastest VPNs. I don't experience any drops in speeds. For best results, try multiple servers depending on your locations. Additionally, Slick was able to bypass the Netflix VPN filter for me. I wouldn't shy away from recommending it. The drawback: it doesn't have a mobile app, so you got to configure OpenVPN on IOS and Android manually.
I use the desktop app and speeds have been good with my trackers. Very happy overall. When I went overseas for vacation it was nice to use US IPs to catch up on shows that I missed. I've recommend to others and they are satisfied.
