Anyone use the BRS 2 Part Doser (1.1 mL Per Minute) to dose their two part or magnesium supplements? I've been running one for 10 months with no issues, until last week when I noticed that it doubled the output for the same amount of time the unit was turned on. Will probably send it back since it's still under warranty. Wondering if others have experience similiar problems with it's reliability. Weird :scratch:.
