Yes, there’s an oring near the top of the Tinymight to hold the stem in place. I like your stem and may be interested in this too. I don’t use my rig that often but it would be a good accessory to have for special occasions.Imagine there is a tiny size range that will work w/ the TM since it uses an o-ring to hold the stem if I'm not mistaken @SquirrelMaster
On a rare occasion I may have had one battery buzz during a session the other day but I think it was in shut off mode as I started my session with two buzzes and was able to get a few draws in with two. Fleeting at best but it was cool to use the TM on two buzzes for a bit (not unusual) but then get one buzz before shutoff.
