I have several CigEasy Elite 
batteries that a friend gave me.  I like them...even though they are manuals.  They last pretty good...about 3 hours for me, but I'm a very heavy chain vaper.  Charge fast.  I haven't tried anything on them but the Elite cartomizers...but I really like those and even use them on my other KR808 equipment.  I don't think they are a "mistake"...they are very nice and closer to cigarette size than my big boys like the Kanger vGo, X2, Echos or eGos!  Nicer for some situations...like stealth...ya know?
