Words of wisdom there ! I agree 100%. BRS sell about the least expensive doaseing pump that actually works well and can be ran of a controller like the Apex or RKE. I personally use spectra pure's meter liter. Pricey but very accurate and easy to adjust. BRS is about as cheap as it gets for two part doaseing unless you are a DIY kinda person.
