What is the speed difference between a Basic account and a Premium subscription for Windows?

Often, we have users inquire about the speed differences between the Free Edition of Hotspot Shield and the Premium Edition. There is no one-size-fits-all answer to this question. The speed will vary from user to user. Factors like your ISP (Internet Service Provider), your actual download and upload speeds, the physical distance to the server, your actual location, time of day, and physical hardware can all have positive as well as adverse effects on the speed.
Also, please keep in mind that when you’re connected to Hotspot Shield or any VPN service, data going in and out of your device travels through the VPN servers first before reaching their target. That's how internet anonymity is achieved and why it's normal to experience some hardly-noticeable speed reduction.

You can try a Premium account for free here.
