I liked that it was easy for new people in my department who did not have any previous knowledge of AEDs or how they work, as well as being able train them quickly! It's also good if you are looking at buying more than one device because there can be some confusion when trying figure out which devices should go with each other (it does ask what model number your current unit has).
Also sometimes after training someone else will use an old version where we need something newer so this helps ensure everyone gets trained correctly by using only updated versions from time-to.- Sometimes units don't always update automatically; however once all users get their own personal ID then everything works great!! Training others easier since our team size keeps growing every year now - makes life much better.
