I see a lot of complaints on here about the v4.3, but honestly.. I've owned it for 2 weeks and have had zero dry hits, zero leaking, and loads of flavor/vapor. Don't have one of the earlier Fogger4 versions to compare to, but no problems to report here.
10 wrap, 28g, 5/64 ID duals = 0.80ohms with doubled over P&C cotton yarn [2x4strand] wick. The trick is to only put 1 or 2 threads of the yarn about halfway down the vertical wicking channels; the rest I stuff around on the deck like a dripper/taifun gs which serves to act as a resevoir of sorts. Holds darn near 4ml too.
Haven't touched my Russian since I got this up and running. Even my Rose2 has been neglected in favor of this $30 atty.
EDIT: Oh, just a thought, when filling I've always held it at a 45degree angle with the fill port closer to the floor. That way the juice spills onto the glass tank wall and not into the wick holes. Apparently, that's one of the problems people are running into problems with the newer version?
