I bought it not realizing it was for the wrong floss company, but I bought the DMC too, so its good. Its really easy to work, just tap the color you have, slide over the little dot from dont own to own, on a bobbin, or need to buy, click over to add a count of how many skeins you have, and boom youre done. I find I dont need a search because its all in numerical order, and even pictures the color beside its number.
(Does that help down there? I hope so.)
