The tool performs great with my large datasets/examples! I enjoy using this app because it is easy enough that anyone in our organization could use without much training / expertise needed from myself or others at work (or outside). Sometimes its slow and takes time before showing results, so make sure your internet connection has high bandwidth & speed otherwise things will get laggier than necessary. Not all features seem fully supported by Ramas yet - some examples aren't working well out of box even though they're part of other apps we have been testing them against previously. We've found many uses within different departments where certain functions may prove difficult if done manually rather then through an automated process which helps eliminate errors associated wtih manual calculations etcetera.
