From 2017.. it's on it's last legs. I've taken good care of it, however I'm not sure what I can upgrade to that's not smok, that's not overly huge but still uses a 2 battery setup, and a new tank in the same form factor. My G Priv 2 blew up, and my X-Priv started crackling with my battery.
I've always used IMR and smok just isn't the best brand with their devices past the Alien.
