The guys in my local vape shop yesterday swore blind that efest make there own A grade batteries now lol and the efest 3000mah 35a 3.7v batts I originally bought are the best batteries I could possibly have for sub ohm vaping ! Surely that's a straight up lie ? Everything I've read online and all that I have learnt off this thread goes against that lol
Vape shop staff will try to sell you what they stock, or what they make the most profit on.
A decent shop will have a wide selection to offer, if they only stock efest then that's all they're going to offer you.
