Review on BreSii Wireless Mouse - Dual-Mode Bluetooth 5.0/3.0 & 2.4G Optical Silent Mice with USB Receiver - 3 Adjustable DPI - for MacBook, Laptop, Notebook, PC, Tablet - Pink by Jon Garcia

This dual-mode mouse is ideal for use at home or on the go. It runs on a single AA battery, and the USB adapter tucks neatly into the battery compartment. You can switch between dongle and bluetooth mode by short pressing the button under the mouse. A long press on the same button starts pairing mode. In pairing mode, the mouse is advertised under two names, one for 3.0 (support for older devices) and one for 5.0, which you can use on the latest computers (use "Bluetooth Smart" for technical reasons. " aka LE). It records well, the battery life is excellent and the best thing is the incredibly low price for this very flexible and very powerful mouse, at this price it's good to have a spare on hand, you never know when you might need it!
