Anybody else tried these yet? I got a new tank from my local B&M last night, and found out today that this is what I have. VERY quiet tank, sounds more like a clearo than a DCT. Have had no issue with my HR predrilled smoktech cartos, but I've only been using it for a few hours. Just curious what others are thinking so far. Glad that no longer will I have to use pliers to remove the tank because it just slides around on the carto instead of unscrewing
