I have a Reo Grand VV polished, that I paid $150.00 for in the classifieds and I hate it !!! I hate that it's only 15 watts. I hate it doesn't have a display with a ohm /voltage checker. I hate that it had to be retro fitted with an exposed fire button, the recessed button was way cooler. I hate the 18350 stacked batteries that don't last as long as a single 18650 battery. I hate that it won't accept a 21mm atty. It's just sitting there on my end table next to my ProVari /R91 combo. Not to mention having to charge the batteries twice a day compared to every other day for the ProVari. Or having to refill the juice bottle twice for each fill of the R91. I pretty much hate everything about this mod., except one. That one thing keeps me picking it up at least twice as often as my ProVari. That thing is great vapor that has fantastic flavor and a rich thick cloud. I can only get that vapor from my ProVari with a good RDA and that's a PITA to me. If only I could morph these two devices into one, I would be as giddy as a school girl. Ah, yes there is the Sun Box E7 and it's very close to what I want. But unless I take a second on my house and am lucky enough to live long enough to actually get one, I'm out of luck. I don't understand why mod manufacturers are not doing more to supply this niche in the vaping community. I even saw a thread that suggested petitioning Rob over at Reo to make a kit type device that the buyer could put their own chip into. It sounded like a great idea to me, but got shot down by Rob before I could add my Amen. For now I can only hope that soon there will be more regulated bottom feeders showing up on the market. Well that's my rant, I feel better now.
