Have you heard anything back @Andre?Great info, thanks @Lingogrey.
Have just checked my turds. They all look ok, bar the last 2 ones I have bought from @Sir Vape, which look like they have the shiny/smooth top ring insulator. Very difficult to see if you do not have an original and a fake side by side.
Awaiting instructions from @Sir Vape before I take off the wraps to see if they have self-adhesive top insulating rings.
