Hello there,
I'm new here and don't know very much, however, I lucked out and bought 4 of these J118 kits to start with (one in each color). The reason I say lucked out is that since buying those, I have tried everything I could get my hands on and all were inferior to this little $50 kit.
I have learned that the only interchangeable part with the 901 is the cartridge. How do I know this??? MY SCREWDRIVER ARRIVED TODAY! Thank You Mr Trog!
The cartridges are interchangeable, but not the atomizers.
The throat hit is superior on the J118, but I think I have discovered a way to modify the SD to deliver a true menthol experience (I used to smoke KOOLs) if it works I will post the $7.00 10minute mod on here tomorrow.
Sorry for rambling, but I'm afraid we are losing far too many Vapors to bad first trys. If my first experience had been e-health, I would have stopped right there and never tried agian,
KATO
