jcalis, I forgot to mention, you can just about get 2 RM2s for the price of 1 hornet.
You prolly got a bit of the strong juice in the cap above the oring. You may want to slide that cap off, pull the ring out (I use a paperclip to pry it out) and wash it all really good, then reassemble.
Love the vape store hobby! Our guys at the local place are so cool, even though they don't have REOs.

I've posted before that they are expanding and hiring new help. So the last time we were there a new guy had to know what I was using.

Just spreading the word, and the word is REO.
Have fun!
