I have a VaporRX, which I believe is the same thing (looks the same) and its AWESOME. Cost me $150 for the unit and 2 cartridges. I used 1 cartridge in about 2 weeks. The taste is unreal, the high is sorta not all too powerful for me. I have been smoking BHO for a while now so I guess when I go from BHO to vaping an E-Cig it just isnt the same strength. AMAZING for stealth, and keeping a slight buzz, but dont count on this getting you blasted... well it didnt at least for me. Very mellow and clear headed high, with one of the best flavors. Also Id have to say no smell on exhale.
If there is in fact a way to fill these up I am gonna be all over it. I am trying to take apart the one I finished already to see if I can put some oil in. But I must say the oil/juice they have in it currently is much more fluid than any bho i have ever had. This was more of a liquid whereas I see bho more of a taffy.
I have not had my clog yet or even feel like it is close to doing so. I recommend it if you got the money and have access to the refills. If I devise a way to refill my cartridges then this device will have me recommend this to anyone who can get one. Also I would say 1 cartridge will give you the 80-100 hits that I was told it will produce.
