After trying the 510, 901, 801, the RN equivalents, and the the KR808D-1 I went with the KR and have been quite happy with it. However, I'm unclear on what is the E9? I had some GreenTech cartomizers that I thought were E9 but someone corrected me that they were not.
What's the E9? What's the difference? Where to buy? Does it work on KR batteries?
Thanks.
