Yeah, Ive spent a bunch of time with this one, got the wicking down, figured out which of my devices/settings can give on demand vapor but still have yet to get the full experience. The learning curve seems to be all over the place, dependant on user, device, juice, and making sure you wick correctly. Or maybe its just me, I gave it an honest try on 8 devices, really wanted my 109$ investment to pay off. After everything I find that given same juice, same intended vaping experience, same device, same everything I reach for one of my rta' or rda with a kanthal or SS or even n80 build first before the Altus. The reason is simple, there is more flexability (user setting wise on a vv/vw, temp control device) in a coil I built myself than the Altus. Though I will say once you get use to it and get the heating element broken in, things get better, but not 50$-100$ better.
