I've been so happy about my new Advken Mantas, but I am still suffering from a bad case of acquisition disorder so I ordered two Fatality M25s sight unseen. I got the first of the two in the mail today and boy was this an impulse that worked out in my favor. Juice control might not be necessary anymore, but I'd still rate it a pro as it gives added protection for tank filling or travel. The dual airflow is a big pro as it allows you to tailor the air and flavor production to your preference. The capacity with the bubble glass is great and it looks good with it on. Building on it was a breeze, and this is the first rta I've had that wasn't a Velocity or at least pseudo-Velocity style deck since the original Kanger Subtank and Cthulhu rta. It's so roomy compared to what I'm used to that I did my first set of dual claptons on it. I bought too thin clapton wire and my build was .40 where I've always built to .22-.29, but maybe that isn't such a bad thing as that means it wouldn't pull so many amps yeah? I'll order a roll of the next size bigger clapton next time to compare, this roll was 28x2/38, and it seems like this wire has ohms per foot that is more like 28ga than the 26 and 24ga I've always used. I'm thinking the flavor might even be better than the Manta as well, but that could just be because I'm excited about the new tank so I'll vape both all weekend to see what I think about that. In any event, both rtas kick ass and I'm not sorry about buying multiples of each. Lastly the machining on this rta is the best I've owned. It's finished perfectly and all the threads and moving parts slide like butter. Costs more than the average Chinese made rta, but no more than a Playstation game which is kind of my yardstick whether I should feel guilty or not. I am enthusiastically happy about the Fatality. Nicest rta I've owned and seems to wick, not leak, deliver a wide range of airflow options, and produce world class flavor all flawlessly.
