Vapour RebeL
Yes, its the cuboo version. It's not loose, but since it's mentioned in the product specs, I thought I should point it out.if it is loose inside, i would recomend you getting that O-Ring cause it keeps the glas stable. Did you bought it with us?
The 'click' that the tube does when inserted to the bottom of the circuit, seems to keep it stable enough.
