got one today from eciggity. I will reserve judgment on the tank performance until a later date. But as for right now it is covered in machine oil. Its so bad that my first build / tank made me gag, wanted to throw up afterwards. This was after already washing in hot soapy water.
Its soaking in 99% iso right now after I boiled it in soap water for like an hour. I might even try acetone if i still taste machine oil.
Mine went for a second round of cleaning last night, and I'd say I finally got it clean. I broke it down and scrubbed it again with Dawn and hot water, rinsed it, and then boiled it for a half an hour. Both times after I boiled it, there was a nice oily film on the water when I was done. I'm guessing most of the stink is in the center screw, but I also smelled it in the chimney sections.
I'm disappointed in Eleaf in regards to the machine oil, because all my other Lemo's came perfectly clean, so I know they could have cleaned it better, but instead rushed them to market.
Flavor is now close to my original Lemo's. I have identical builds in my Lemo 2 and my Lemo Drop, using the same liquid, and the Drop has sharper flavor.
Vapor production wise, the Lemo 2 wins and I'm loving the external AFC and top fill.
