Couldn't find a thread devoted solely to this topic and their benefits and disadvantages so...
Added free Chrome extension DotVPN then read that its disadvantage is security, ie anonymity, so bought a yearly subscription ($8.32/mo) with expressVPN. Problem with both is that they slow down internet transactions to practically 1 Mbps and before VPN I was getting over 70 Mbps. Like TD times out before it even opens. So I've disabled both but plan to enable them in time for any critical downloads or uploads. What's the diff?
