On a serious note...
What do we expect out of this battery? I dont own or use any vapes with a non removable battery...and I know overall battery life is a complain people have with those types, you know like mighty/crafty for example, over time the battery starts to suck and its a whole process to restore it.
Also saw how its been opened up and theoretically should be able to be user-replaceable but who knows. Just would be a bummer to buy this thing and then a year or two from now it's gotta be sent back for service for a shitty battery or you have to buy your own battery replacement pack etc. etc.
