The battery itself is fantastic, I just wish the green were more green and less a turquoise, but it doesn't take away the fact that the battery does a great job.

Very durable battery with a great charge life. Only thing is they are a little long which can make discrete vaping a bit more of a challenge. Otherwise a fantastic battery
