For the most part ok, finds most products, even eastern european, but units of measure are not very well included. On the apps like fitbit, you can choose 1g, 100g, piece, and other units of measure. In MFP, dropdown choice of units it seemes to be just imperial cups, servings etc. So if you are used to metric system, you need to find a way to make it work for you. Sometimes for eg. if you just want to log 30g of particular cheese, you have to put 0.3 of the 100g serving
