Jumping right into it. Kill switches. Supposed to save you from leaking IP when VPN drops. Sounds great in theory. In practice, it's another layer of the unknown. Tested a bunch of VPNs while streaming and torrenting. Some kill switches work like a charm. Others leak the second you sneeze too hard. Real world tests: Netflix? Drop connection, IP leaks faster than a sieve. Torrenting? Same deal. Not a single VPN passed all my tests perfectly. Seems like a toss up between the VPN that kills the connection promptly or the one that kills nothing at all. Funny how the providers brag about their kill switches but never tell you about the times it fails. No one talks about the data showing how often they actually do their job. Work in progress but honestly, if you're relying on a kill switch to hide your tracks, you might want to rethink your privacy game. It's like insurance that you don't need until you really need it and then it's too late.
