I like how quick it was for me, after i set everything up with them they were able too connect in no time at work when connecting from home or my phone which saved alot of hassle as well! Also very simple interface even though there are some features not available yet (i think this will be fixed soon).
The only thing id say dislike about smartvpn so far its their pricing system because if u dont pay yearly then sometimes connections slow down but other than thats nothing really bad either way just try out different plans/packages before deciding what one suits ur needs best!! It has helped save us tons amount money while using VPN's online due security concerns we have had over our network being hacked etc also helps keep things private between co workers who may need privacy without having thier own personal vps setupetc.
