Why the Razer Atheris is the best portable mouse

Should you be a fan of Razer's already well-established PC accessory collection, you'll dig the Atheris. It's compact enough to squeeze into the tightest spots in a laptop bag but offers the excellent performance of a full-featured desktop mouse. Utilizing Bluetooth LE and 2.4GHz wireless technologies, the peripheral can quickly connect to a Windows PC with an available wireless card or use the included dongle.

There is one downside: the omission of the Razer 5G sensor. What's included inside the Atheris is an optical sensor, which actually offers solid levels of accuracy with up to 7,200 DPI. It's capable of reading up to 220 inches per second and can handle 30G acceleration.

Because this is a portable mouse, we've got to talk about battery life. Sporting just two AA batteries, the Atheris can last up to 350 hours of action. Other features include adaptive frequency tech, tactile scroll wheel, ambidextrous, five programmable buttons, a polling rate of 1,000Hz, and support for Razer Synapse.

The best part is the price, and at just $49.99 it's not going to break the bank.
