Very easy to use. Insert the battery, connect the USB receiver to your device and wait less than a minute for it to sync. You are ready to go! There is also storage space for the USB receiver in the battery cover. I couldn't decide between this model and the more expensive ones, but I am very happy with this choice. It's cheap and does exactly what I need! I've used it with PowerPoint slides and shared presentations in Microsoft Teams. Works very well with both!
