I've never used a Cirrus, but like their disposable Flings and have been dying to hear how the Cirrus is from a real person. I hope you update with a review! I wanted to switch to a smaller more convenient system so I just ordered a Smokeless Image Volt, but I was very curious about the Cirrus. Lots of
reviews on their site say the batteries last an insanely long time (I've seen 6-7 hours for the Cirrus 3 and up to 10+ hours for the Cirrus X3), but it seems people on ECF don't like the company because I guess their kits used to be MUCH more expensive. Anyway, I hope you like 'em.
