I am just trying to figure out how to open up the UWELL crown 4 mod because I have been having problems with it just cutting off for no apparent reason at random times during the day. I saw a pretty good post that almost led to me solving the issue however I cannot post yet because I am the new guy. Anyhow, been vaping for years now. There are no videos that I have found showing how to get into this mod to check for leaked juice or damage to circuit board. Any help would be greatly appreciated.
