Only built it 30 minutes ago, but impressed so far, has good weight to it, but I did order the kayfun top fill cap too, which glad I did, as to start with I did try to fill from bottom screw, and seems the chimney restricts it filling, so won't be filling it from the bottom, but then I did order the top fill cap for the reason of not having to remove from a mod to fill.
I am even impressed by the drip tip that came with it, normally I leave them in the box, but this is beefy wide bore drip tip, so has stayed on.
I did not measure how much juice it takes, but is a lot more than the orchid v1 I got already, only complaint to it so far, of course tank is not glass, but also small, so will be hard to actually see when you are getting low on juice without tipping it, I probably would of thought of getting another one, but found out about 'billow' last night and pre-ordered that one, which I think well top the orchid v4 for me, seems a cross between the lemo and the orchid, my 2 favorite atties right now
