The Bad: The big con that I've found is build quality. When they are good, they are great. But one of the two that I ordered arrived with a broken glass tank. I contacted the eBay seller and he immediately shipped me a third unit. It arrived in good form without a broken tank, but the threading on the bottom cap was so wonky that it wouldn't screw on all the way. Thankfully, I still had the bottom cap from the broken tank and used it with the new tank. If it had just been one or the other issue, I'd simply chock it up to chance, but both together have me really meh about the inconsistency of Chinese quality control. Not a single one of my KangerTech Protanks have had a single part that wasn't perfect on arrival. That said, I paid less than $10 each for these Aspire tanks. So they are half as expensive for a glass and steel tank that holds an equal amount of e-liquid as my Protanks. I suppose you get what you pay for.
The Good: When production quality control isn't an issue, the new atomizer technology is really pretty amazing. I've run four different juice flavors through my two tanks and have noticed one HUGE difference in these new coils. It doesn't seem to matter how thick or thin my juice is, I haven't been able to get these tanks to gurgle or flood. Considering that that is an issue that I've faced even on good days with my Protanks, that is a pretty amazing thing. And it must be making waves in the industry since KangerTech has copied this coil design for the new Protank 3. (Of course from the cynical marketing business perspective, the new coil design also prevents rebuilding of homemade coils...which means a continued revenue stream for the production company in the way of replacement coils...so it's a double-edged sword here.)
If I were asked to filter down the single greatest aspect of the Aspire tanks, it would undoubtedly be the consistency of vape. I haven't faced flooding. Vapor production is great on them. And I'm getting some of the best flavor I've had on any tank. I can turn my voltage up quite a bit before I get any burned flavor, and I just get ootles of great vapor with solid flavor.
So am I still convinced that the Protanks are my favorite? Well. That's a tough call because I love these Aspire tanks too. What I really love the most about the Protanks is their heavy, solid, stainless steel and pyrex glass. I haven't used another tank that I enjoy more when it comes to the feeling of it pressed to my lips. What I think I'm really enamored with in these new Aspire tanks is the new coil design. I do think that it is the revelation in design technology that the manufacturer says it is. And if I combine those two things I love into one unit, it seems that I may need to find myself a Protank 3....or at least a nice stainless steel drip tip for my Aspire tanks.
I will buy more of these. Zero doubt. When they are built right, they just seem to work really really well. Just buyer beware that you may get a dud here and there.
