The best thing about celenon is its ability to track multiple subjects at once with ease! It can be very useful for tracking patients in hospitals or other places where there are many different staff members working together as well has being able too keep an eye out fo things like missing equipment etc..
I haven't found any downsides yet but have heard it's not always easy nad time consuming when you first start using this system so try before buying if possible!! Tracking medical assets/equipment while also keeping everyone safe from harm by knowing exactly what items they need next (or even just who needs them).
