Probably....It doesn't bother me. I just swap fluids puff out the blend flavor then vape away most of the time. I don't even change wicks most of the time between flavors
I do usually just plug the air hole and blow down the RM2 getting the juice out of the tube and most likely cup though while swapping bottles.
