I love that it's easy to create custom rosters and share with others! It is very intuitive and has great customer service support too! Honestly nothing so far. The product works well overall but sometimes when you're trying to add an employee or update their information there can be some lag time at times. That being said, not much of a problem since we don't have many employees currently. Creating custom rostering templates is super simple as well. We've been able to get our team organized really quickly using this tool.
