I have a aws Gemini 20 scale. I just bought this a month ago. This is the 4th one I've bought that I like that actually reads milligrams. The rest I wasted money on, don't read low amounts. Does anyone know a way to fix these when they flash different numbers with the same mg of powder? I'm so frustrated by these scales. I use the same spoons and scoops to make it easier and I just write it down.
