If you do soak it, disassemble it first, then soak all the parts and reassemble
There are nooks and crannies (under ceramic) inside the RM2 where liquid will be trapped
And can take quite a while to evaporate
My batteries didn't come in today so I couldn't use the grand but I threw a 1.7ohm micro coil on the rm2, wicked it up, and put it atop my mini134. Works PERFECT! (Didn't clean it) vapor and flavor were both great and the draw is perfect for me. I sure hope I have batteries in the mailbox tomorrow. Looking at my first grand for two days now and not being able to use it is cruel and unusual punishment
