I love that it's so easy to use, you can create your own custom formulas for any situation! There is nothing about this product that I dislike or would change.
It has been extremely helpful in my daily work with our clients. The only thing I wish was different is maybe there could be more options for how many products are added at once? Sometimes we have multiple customers who want to add their products to one report - but they don't all need to show up as rows of data. This allows us to do just that without having to manually enter each individual item into the formula.
