Review on Fox Run 4892COM 4 Ounce Measuring by Regina Vere

I ordered this hoping it would be accurate enough but it's nowhere near. For example, we know that 1 ounce = 29.574 ml. That means the 1oz mark and 30ml mark should be almost identical, and yet the 1oz mark is about halfway between 30 and 40ml, so around 35ml. For what I do, these 17% incorrect measurements produce an uncertain end product. I stopped there and did not test and compare other measurements. I have used 2 other medical dispensers, first to compare them to each other and then to this product. If you need accurate measurements, this product is not for you.
