I bought a shot glass at Bed Bath and Beyond. It was around 3 dollars and it is marked in oz and other various measurements. I put it on the scale on oz, then hit the tare button and pour using the scales weight and not the shot glass. The scale is key, so even a plastic measuring cup works too! I am still testing too, and not having any luck yet on the wicks! Well, I am waiting on 5 new testers to cure.
