Have been using these Efest batteries for a long time now, they charge quite fast but they don't last as long as you'd think. Saying that comparing to other manufacturers and they all last about the same between charges.
These batteries tend to last me 6-8months before replacing but again same as most manufacturers

After reading some bad press around efest and the performance of their batteries I was apprehensive buying these but I have been pleasantly surprised by these.
The battery performs well in my sub ohm devices, my only concern is that it doesnt seem to last as long as you would expect given the capacity of the battery and the battery reader on my devices seems to move up and down randomly throughout the day when indicating charge. This doesnt seem to have affected performance however.
