Just got it 3 days ago and I'm loving it. I went with the Tropical Green. I messed up and ordered it then read about the RM2 and bought it the next day. Just came today wrapped a .8 ohm coil and It's firing like a champ. I'm so glad i looked at this forum, I bought a ego twist, MVP and a Vamo. I work HVAC new constuction so i wanted something that could take a beating, I don't want to say how many kanger protanks I went through, lets just say I wish i would have found you all sooner just thinking of the money i could have saved. Oh Well. Thanks again
