The other reviews sound weird to me. I've run this measuring cup through the dishwasher, washed it in the sink and poured dozens and dozens of cups of coffee, microwaved them, measured oil, milk and other things with this and never had the numbers wash off. I'm happy with my purchase!
My measuring cup lasted me a little over 2 years before the numbers and lines started to fade. I am not sure about the newer products but for the money, as an avid baker I was VERY happy with mine and would not be hesitant to purchase another Anchor Hocking glass measuring cup.
