This is a wonderful tasting butter spray! I use it all the time, and it helps you to manage putting too much butter in things, like I have a habit of doing with things like cooking eggs.
However, with that said reading some of these reviews, especially those who are very sensitive to fat intake, need to understand this is NOT a zero fat product. 1 single spray, which is a serving size, has such few calories and fat that they are required to label it "0 fat" and "0 calories". However, you should understand if you douse foods in this produce, you will certainly add a lot of fat content to the food. Just please, be aware of this! It's not really the companies fault either.
But as for the product itself, like I said, it's very tasty, very good, buttery, and hits the spot.
