Hey all! I have been vaping for nine months now, and I have stuck with the 510 and Kr8 only. I have just tried my first LR510 atty and I love it! I use it with my ego. I just had a stupid question, I have been hearing a lot of good things about the LR 306 atties from Cisco - and I wanted to try them. I have read about people using them on their ego. If I pick a couple up to try will I need an adapter to go from my 510 fitting on my ego to the 306 atty? Or are they interchangeable? Sorry if this is stupid, you'd think as long as Ive been vaping I'd know the answer - but Ive really never used any other atties. Thanks in advance!
