I see mixed reviews on the Azeroth. I used it today for half an hour at my local B+M today. I had the day off. He let me build and wick his own Azeroth to test it. The Goon deck makes building easy but the screws are a bit too short for really thick wire. You can fit a slimmer alien or clapton in though with no issues and the deck is big. I've heard some people had issues with tolerances. I did not on the one I tested. Everything fit fine and the o-rings had just the right amount of tension. I have a Limitless Plus. This looks better especially in black. I like a good looking tank. I ended up buying one.
I'm probably a poor person to be judging. I put a Troll V2 on my new Satan series mod. I have at least four high end attys sitting about but picked the Troll anyway with a single coil build and stuffed the deck with cotton. I like a few lower end attys a lot - the Troll V2, the Hannya postless, the Velocity by Tobeco. Doesn't mean I don't like my Fuel V2, my Kennedy, my Petri or my Tugboat. But I would use my Tsunami 24 as often as my Kennedy 22.
So I'm thinking of buying the Dotmod RTA but really - is it better than an Azeroth? Or a Tornado nano? Or my favorite - the Serpent mini. Price does not determine how good a an atty or mod is always. The Boreas is now cheap as chips all over the web. The Satan series mod cost me less than 100 dollars. A Pinoy not Chinese series mod and it dead cheap. I have mods that cost 400 dollars and are not as good. The piglet cost 120 dollars is not better than the Satan.
