I have used competing PureVPN before, and I had hoped KeepSolid would be better.

KeepSolid is rather slow at connecting. It does not connect automatically (even with auto connect enabled, which is disabled ever so often), and it disconnects every now and then. It does not have a list of your preferred (or even last used) countries, so you need to click a lot more. It does not remember your password, and Firefox cannot autofill the field.

The VPN speed is OK: 100 Mbps.
