So, I just got this today and have been vaping with it for a bit now, enough to leave my impression here. I have and use an OBS engine nano, Merlin mini, all the Goblin minis, Coilart Mage GTA, Digiflavor Fujison, Serpent mini, Serpent mini 25, Serpent alto and now this Serpent RDTA. My impression so far is WOW. Super easy to build right out of the box, looks good even though they should made it a 25, but the flavor! This thing is my new favorite. The Serpent minis are awesome, the Alto sucks, neat tank/idea but the flavor is weak. This one though, just WOW! With the correct screwdriver the screws are fine and I kind of like the way the leads mount to the deck. GET THIS TANK!
