I've just found out that Janty USA stipulate that their warranty is void if you do not use their juice with their hardware. This ties you into a contract for consumables for the duration of the warranty and makes a difference to the value for money calculations. Ruyan say this in their warranty conditions too.
I'm not sure how to work out the yearly costs but for Janty there isn't a big difference. For Ruyan you get charged an arm and a leg for cartridges so the costs would be more noticeable.
What would make a significant difference for me though would be the limitations of juice available. I like being able to try different brands and flavours and being able to make my own. Another thing is that neither Janty nor Ruyan have published toxicology reports on the safety of their juice, nor do they prove that it is checked for tainted ingredients. They do not even package their eliquid in properly marked and sealed containers, if it was foodstuff it would not be allowed to be sold.
They expect us to be tied into a contract to use this juice ... I might buy it voluntarily but being obliged to buy it is a totally different matter.
