What is this Auto Ego that you refer to, DSL?
It's a regular Joye Ego with the 510
threads, but has no manual button. Has been available for probably a year but everyone has been cautioned about
juice in the battery with automatics, so I think people shyed away from them. I've had no problem with about 4-5 in rotation (I don't drip and only have used good non-leaky cartomizers). I also clean the threads everytime I change or charge. I have one 650 stainless from Janty, 3 650 black Egos from Cignot, and one pink 1000 tornado? from Totally Wicked. All Autos! That being said, it is difficult to find the Joye Ego style Automatic from suppliers and especially in colors. Cignot has been my best source. Vicki there use to have the 1000mah and 650mah
batteries in Black, White and Stainless.
