Jimi, the SLBs that I receive definitely have a plug. This is the item I purchased from LiteCig a couple of weeks ago

Here are pics of the SLBs
The BOGEs only have the white end cap.
There is no way I let these things dry out. When I opened the last burnt one, the filler was saturated fully to the point where I could wring out the
juice!

Added info:
OK, I just took apart a new one. The heat coil glows red in 2 seconds or less. Tried another one and burnt taste after 12 puffs or so. Now in the trashcan!
