I haven't heard much on them either. I think someone ordered a couple of the ego autos from LF but I haven't heard how they are working.
That setup looks real sharp JJ.
Okay JJ, here's my quick report on the Ego Auto from LF. Shipping pretty quick and not too expensive, it was $2.99 to Oregon for the two batteries I ordered. I ordered Wed. morn and received Sat. afternoon. The batteries were 13.99 each with their 20% discount. I stuck them on my Ego charger and they were charged within 2 1/2 hours like a standard Ego. They are 1/4" longer than my Joye 650 autos, so when paired with the Echo-E cartomizer they are the same size as the Echo with an Echo cartomizer. The tube is longer with 5 small holes for the blue led to shine through. I like that the lights are visable but not large like the Echo. The batts are not sealed and the air hole on the plate resembles the Echo in size. The draw is tighter then the Echo (like my Joye Ego autos) but the auto switch seems more like the Echo.
I think I'm concluding that the draw is tighter because of the connection on a 510 since the cartomizer fits over the connection, where the Echos sits flat on the 808 connection allowing the slots on the Echomizer to draw more air through them hence the airy draw and noise. Maybe that's why the new auto Janty has an adjustable air ring?
All and all, I think for the price and workability of an Ego sized 510 auto you should give this battery a try. Of course I can't speak to their longevity yet. Hope this helps.
