Got my Revolver Elite in yesterday's mail, and it's... pretty good. I'm not totally in love with it yet, but maybe that'll come in time.
The PCC is, by far, the best I've yet seen. I'm not crazy about the white plastic and busy black graphics, but visual aesthetics aside, it's quite brilliant. It has the same footprint as a blu/Volcano PCC, but is about a quarter-inch shorter. The hinge is sturdier and on the back, which means the top flips open 180˚, allowing easier access to everything inside. The assembled e-cig pokes up a bit higher than the charging battery and the carts, so it's easier to identify and to remove.
Pressing the button on the front lights up the LCD charge meter in blue so you can see how much battery life is left in the PCC. Pressing and holding the button with a battery screwed into the charging slot lights a green LED, then flashes the LED on the battery tip, then turns the green LED red to indicate that it's charging. After a couple of seconds all the lights turn back off, and pressing the button again shows whether the battery is still being charged: a red light means it's still charging, no light means it's done. The PCC itself charges via a standard USB-to-mini-USB cord, which is easy to replace if you lose it. If I find I need to recharge the PCC at work and my cable's at home, I can just grab one off, say, one of the digital cameras.
The Elite itself... well, it does produce very good amounts of vapour for an 86 mm e-cig, but to do so, it runs very hot. Uncomfortably so, if you hit it long. And it's blanching out or scorching flavours just like my 510 because of it. I switched back and forth all last night, and the same liquids in the Elite don't taste nearly as good as they do in the blu. That's probably my biggest gripe so far. Maybe that'll improve as the atomizer breaks in, I don't know yet.
My other gripe is with the carts. This is my first time using 401 carts, and I find them very frustrating. The inner cart is terribly small, especially for an e-cig that runs so hot and therefore sucks down liquid like crazy. Worse, said inner cart is black (making it harder to know when it's filled properly) and not flush with the sides of the mouthpiece, so it's much more difficult to push back down into the mouthpiece with a paper clip. I've already modded a 306 cart to work with the Elite, and so that's helping quite a bit.
Time will tell, but so far I'm lukewarm on the Elite.
