I finally gave my KF nano another try, since I use the good japanese cotton now. It's vaping just fine, but I think I'm just spoiled with my Achilles; I just can't taste anything.

Well... I taste the cotton, and it's not burning, but... no flavor of the ejuice. Which really peeves me; my favorite Achilles has damaged threads, so I'm having a hard time getting it to screw into anything; I have one 510/ego adapter that it will still screw into, and I'm using a thread cover so it doesn't look totally goofy. But I was really hoping I could get that KF nano vaping well, to help me hold out until I can get a die and fix the Achilles' threads.
