Ridiculous to say it but it's the cheapest one I own - a BF Smokeless Owl coupled with a Terminator Squonk box. I bought this one at the pre Chinese New Year Sales for sweetie money not realising the thing came with an attie - I simply wanted another squonker to use as a beater.
While waiting for it I read up on it, found according to one reviewer it was a time bomb waiting to go off, but when I checked it over thoroughly and metered it after it arrived and having found no loose or exposed wires, I decided to give the mod a try anyway... and it was fine.
Poking about in the box in which it arrived I found the attie, as well as a spare bottle, a coil jig, a couple of prebuilt pre wicked
coils, o rings and a screwdriver. Again
reviews said it was rubbish and couldn't produce a good vape in a month of Sundays.
Feeling sorry for it I built a 1.2 ohm coil, wicked it and fired up - to my mind it works like a good cigar, has plenty of flavour with the right liquid and certainly produces plenty of vapour.
So there you go - "Whoda thunk it!"
That said it's not one I'd suggest for beginners either.
