Well, time for me to commit the blasphemy of admitting that I've decided at long last that feeder mods are NOT my vaping weapon of choice. Yes, I own three bottom feeders (2 Phids and a 2nd-gen Wetbox with the sealed switch), and I admire many of the current crop of artisan feeder mods (REOs are all mechanical and built like tanks, Phids and Ali'is are well-crafted, Brian's Red Sky feeders are well thought-out and beautiful, etc.). But I'm one of those taste bumblebees who like to flit from flower to flower---I vape up to 20 different juices every day. Swapping out bottles gets old fast, especially with the current generation of improved cartos (dual coils, Boge LRs, and Ikenvape Gold V2s) that can be screwed off and on in seconds.
I do keep a whole slew of PVs at my desk and bedside, all loaded with different juices, but I find it simply more convenient to swap cartos and tanks when whim dictates rather than changing bottles---especially bottles of different sizes (3ml, 6ml, 10ml). I keep about 30 labeled 3ml bottles of my current favorite juices at both desk and bedside for quick refilling/topping up, so---for instance---while a REO Grand is a terrific mod that with that powerful 18650 hit, the 6ml bottle is a deal-breaker for me.
No criticism is intended here either for bottom feeders mods or those who love them. This is purely a statement of my personal preference.
The whole "cottage industry" of vaping is expanding so fast it makes my head swim. Between all the recent tank PVs coming out of Chinese factories (eGo-T, iGo, Go-Go, Echo-e, 510 tanks, etc.), the increasing stream of high-end feeder mods (like the soon-to-be-released Eclipse and down-the-road JModTronic), and the continuing evolution of beautiful hand-crafted wood mods---not to mention the availability now of a wide range of absolutely amazing juices---we seem to be reaching the point in the industry's development where vapers beyond the novice phase not only have a plethora of interesting choices, but can be somewhat more certain of getting products that actually work the way they're marketing hype suggests, without the necessity of endless fiddling and major user-modification to enjoy some satisfaction and ROI (return on investment).
Here in this bright, shining space---after the bare bones beginnings of vaping and the early teething problems, but before the possible legislative crackdowns of governmental control freaks and more ominous, longer-term shadow of global monetary/economic collapse---it looks to me that vapers have it pretty darn good. For the moment, anyway.
