Aha!! So our friend WillSucceed finally admits to loving C-Flex! .WillSucceed wrote:I use my RemStar with C-FLEX (set at 3!) to blow out the tubing on my 420E each night before I connect up. AFter reading some posts about people finding a bug in their hose/mask, I blow my hosing out every night.
Having the C-FLEX set to 3 REALLY helps!
