VPN

I’m still not totally familiar with VPNS but I discovered this thing I’ve been paying for, for 4 years gives free VPNs. So I just turned it on. Only problem so far has been that things will just grind to a halt while it switches servers or whatever, then it picks up again. So there’s some lag with sucks for gaming but you can turn it on/off as you wish. You could just turn it off while you game too. Thoughts about VPNs?
