I normally enjoy your reviews, but if I may offer some constructive criticism, I'm a little distressed by your statement that "type-A tanks are for novices," and "most people grow out of them." I use type-A tanks (among other types of delivery systems) and I've been vaping for over 3 years -- despite what my sig and ECF join date imply, I wouldn't consider myself a novice at this point. For me and many others, this type of tank system fills an important niche as it is more portable, durable, and convenient than many systems on the market. I realize that it ultimately boils down to personal preference and these tank systems seem to inspire love/hate reactions, but I don't think that necessarily makes type-A tank users novices. Furthermore, there are several notable rebuildable devices that use this tank system such as the Bulli A2-T (which I use), the Mark-T Infinity (which the Vision Eternity is clearly based on), the My-T, and the Patriot. These are not "novice" devices, and I doubt many users of these devices would consider themselves novices either.
One of the major selling points of the Eternity is that, like the Mark-T Infinity, it can be used interchangeably between tank mode and drip mode. Now I realize that this review is an exception since your sample broke, and my point is not to defend the Eternity here. However, hypothetically (had your device not malfunctioned), wouldn't it be important to review the device in both modes, since that is one of its defining features? If, for example, I were to review a Z-Max and I had no interest in variable wattage and only reviewed it in variable-voltage mode, we couldn't really call that a thorough review. Again, I don't mean this as any sort of personal attack and I certainly see that the fragility of this device probably didn't warrant a more in-depth review, but I hope that if and when you review Eternity v.2.0, you'll start from a more holistic and open vantage point so that we "novices" can see how it works in tank mode!
