HI all, it's been a while.
It's been a while mainly coz I am settled with what device I use, what juice, what batteries etc.
And the device I use is indeed the Eleaf iStick. You're right, they look sturdy and I have one piece of advice to make them last longer: Don't allow the battery to drop into the mod. PLACE them in, otherwise the bottom plate of the mod starts to fall away.
There, I'm done.
Hope you're all well and staying safe,
Jed
