In our tests, we saw little difference between the two types of connectivity during basic work tasks.Taking notes used to be so simple. But the latency difference between Bluetooth and RF, which is measured in tenths of a millisecond, is probably negligible for productivity. Gaming companies like Razer and SteelSeries claim RF connections have the advantage, and that is likely true for gaming.

Unfortunately, there’s little agreement around which connectivity method is faster. A mouse’s responsiveness is even more critical when gaming, where quick reflexes can be the difference between virtual life and death.

If your input doesn’t register onscreen nearly instantly, you productivity will quickly take a hit. The main concern with wireless connectivity is latency. For this reason, some mice come with a small compartment in which you can store the receiver when it’s not in use.

If you lose it, your mouse won’t be good for anything but a paper weight. If you don’t or can’t keep the dongle plugged into your computer at all times-you only have so many USB ports, after all-you’ll have to vigilantly keep track of it. This is a plug-and-play process and the mouse should talk to the receiver-often called a “dongle”-as soon as you plug it in. Wireless mice that connect using radio frequencies come with a USB-RF receiver that plugs into a USB port on your computer. Most modern computers ship with Bluetooth support, so if you purchase a Bluetooth-compatible mouse, you’ll just need to pair the two devices to get up and running. In lieu of a cord, wireless mice connect in one of two ways: via Bluetooth or radio frequencies. What to look for in a wireless mouse Connectivity
