The Lemo is a fantastic rta - I have three. 
The only problem I have had with them is some dry hits with max VG juice, but that may be my build/wick. With 50/50 it vapes fantastic and only dry hits when I take a loooong lung hit or really chain vape the heck out of it. That is with a 1.3 ohm coil. I have never gotten a dry hit using max VG with a stock Kanger OCC in any of my Subtank Minis.
