Not sure if these have been brought up before but one of my local b&ms just got these in

Anyone know how good these are? They're selling for 15$ and apparently is a 2000mah 40A battery. Going to look for more specs but if anyone has experience with these and cares to compare them to say efests or sonys I would welcome it lol
They are by vaporcells and called vamped
