Thanks for the quick (immediate) follow-up on this. FWIW: In a related thread, another eGo/Cartomizer user actually peeled off the cartomizer wrapper/sticker; and it fit inside the cone a little better, and improved the airflow. However, as i understand it, a carto without its sticker does not make a very comfortable mouthpiece.
Correct.. it does not! But, you can cut down a 901 cart and stick it in the end of the KR808D-1 cartomizer. It fits nicely and for many it makes for a more pleasing experience than the round cartomizer body. I use the 901 tip on all of my cartos.
