It sure looks like the Titan Mega 510 from TW. I have several of those. IMHO, what is better than a 510 atty would be a 510 atty that has a consistent lifetime. I have copper attys from TW that have been working for several weeks, and some black ones that bought the farm in less than a week. Of course, it could be that I was mistreating them...flooding and clogging them a lot from failed cart mods, soaking them in 100 proof vodka (maybe I shouldn't), and running them too hot. Now I'm using the facial sponge mod, which is really awesome, and they are acting like they are going to last a while. The filler wicks really well, no little threads, and holds the fluid correctly, so no leaks or floods. It just seems they are working better with less effort, so hopefully they will last longer. Education can be expensive, but live and learn.
