After one week, I'm still happy with the kit I got from
ovaleusa and the response from Trevor to customer questions is excellent. The batteries are lasting an
astounding 12-13 hours of moderate use! I attribute this to the efficiency of the atty/tank combo; I can get a satisfying mouth-full of vapor in less than 4 seconds of batt activation.
There is one downside that may affect the decision-making of others: The atty (according to its designer via Trevor) does not process juice with a high VG content very well. Using 60PG/40VG is pushing it, 50/50 will likely cause wick clogging and a burnt taste—70/30 is the optimum juice choice. (For my more flavorful VG juices, I use my 510 atty.)
To fix a clog/burnt taste or otherwise clean the atty, soak briefly in warm water, blow out from the battery end and air dry completely. Dry burning is not recommended because it may affect the wick material on the reservoir end. The hidden bridge is large and not covered in mesh.
I'm not sure I entirely understood the designer's description of exactly how the tank works—English is definitely a second language for him—but it seems to me that he said the flow of juice is controlled by the inhalation of the user. If you inhale too hard or in rapid secessions (hot boxing), this will lead to flooding the reservoir below the wick. Inhaling too lightly will cause the wick to become dry, reduce the amount of vapor and possibly cause a burnt taste. Learning this caused me to have a phase of self-consciousness similar to when I started vaping... ;-) A gentle, steady inhalation gives me the best result.
