I decided to break out the ol tfv8 tank with a new coil and juice after only using rdas for a month(troll v2 and dead rabbit). the taste is ok but a little off, it feels weak and the clouds are small. not being to impressed I let it sit for a week, went back to vape it yesterday and the flavor was disgusting. for 30bucks I have enough coil and wick to last me over a year. I'm glad I don't have to buy crappy coil heads anymore, what a waste.
