Hmm. My experience wasn't as positive. I've owned two of these; the Standard Voltage (3.7v) and the High Voltage (6v). True that they proved to be reusable, but unless using very thick juice, say 100% VG, they are very leaky. They can only hold between 3 and 5 drops at a time and that amounts to about 4 drags for me before needing another dripping. Considering what I paid for them I wasn't too happy. I jumped on the bandwagon with these guys when it was all new. Had all three Alpha mods, and have retained two; the UltraMax and the UltraLite. They are pretty and the UltraMax still sees use for other vaping, but the 10440 (UltraLite) hasn't seen much use due to the lack of battery life. I keep it as a memorial of vaping days past I guess. Recently I found my LV atty had cracked itself since I did not rinse it out after last use. The brass and SS reacted and the corrosion growth cracked the SS tube. Didn't expect that. I wanted this company to succeed considering its a USA outfit and I thought they were bang on innovation, but then that Cera thing came along and I couldn't get behind it, especially after they phased out support for the original platforms after constantly saying "lifetime" product. Seems they have had a rough time getting their identity straight - and definitely misinformed me on several instances on what to expect from the devices. Of all that experience at least I have that UltraMax still in use, but not for e-juice. So it wasn't a total waste. A lot has changed since those days, and rebuildables sort of trump reusables especially now that anyone can get a decent tank - back then tanks were only a greek glimmer of a thing called a genesis. OK I'm getting sentimental now, and will put the keyboard down.
Short answer: you aren't missing anything.
