@RoboMan Your welcome!!
As for your question: For me, it does not slow me down! However, my internet speed is right around 20 MBPS.
Anyone else can confirm? I have heard from some that it slows things down a bit or there is a magical cap off. With this being said, this VPN is one of the most secure VPNs out there. If speed is really needed then maybe another VPN is needed. However, this VPN is for security and designed for security.
Please take a look at this comparison:
ExpressVPN vs Windscribe Feature Comparison - Windscribe
As you can see Windscribe is much more advanced than ExpressVPN. However, if I had to choose I'd go with Windscribe VPN, PIA, Express, or Nord. Those are the only true secure log less VPNs. With this being said, Windscribe beats them all out with the features that this VPN has.
