Question guys. I've done a lot of back and forth checking out various RTAs on youtube and I think I'm about to buy a Goblin Mini V3 in black. It's £14 at Totally Wicked. I like the option of swapping out decks but will probably mostly use the single coil deck. Is it a good tank? Most reviews seem good but I've come across two instances where people said the juice control doesn't close completely and a few that said it leaks.
Also, when I want to rewick or rebuild without emptying the tank or losing the juice, I guess I would just unscrew the deck and stand the tank upside down so the juice doesn't come out? The only tank I could find that seems to completely shut off juice when removing the deck is the Bachelor and Bachelor Nano by Ehpro. They seem like good RDAs, quite nice looking, but they're postless decks which look a bit naff and remind me of the evod style.
If you want single coil, the only answer is the OBS Engine Nano, you don't need juice control as it's top airflow and Stevie Wonder could wick it properly.
