I like how easy it is to use this tool for our team of over 30 people across multiple locations in many different states as well! It's very helpful when we are all remote working together during Covid-19 but also great that everyone can still be present with their work even though they're not physically being there by us anymore!! The only thing i dislike about kanbantone or other tools similar would have been more options/features available (ease using).
We've used KantoOne mainly because its free - no cost associated so far since implementation has started :).
