I like that it is easy to use, even if you are not very familiar with Excel or formulas in general! It's also relatively cheap compared to other software (but still worth every penny). The only thing i dislike about this program so far has been some issues when importing data from another tool we used before - but they seem resolved now :) We've realized our biggest problem was having too many options available at once while working through different scenarios during planning meetings/presentations etc., which can be overwhelming especially since there were no filters built into any version yet back then either :D This helps us keep track all those possibilities quickly without getting overwhelmed as well ;).
