I like how easy it is for me as an engineer (and anyone else) with no IT or network experience, can install/use this product without any other technical support from someone who knows what they are doing! This also limits my ability do get help if something goes wrong that may be caused by myself not understanding some of their documentation - so far we have had nothing go "wrong" but more likely due too our own lack of knowledge about using VPNs correctly when setting up virtual networking solutions such us theirs etc..
