Dell MS3320W Mobile Wireless Mouse vs Microsoft Bluetooth Ergonomic Mouse

Buy the Dell MS3320W if you want a small, light travel mouse with dual 2.4 GHz and Bluetooth 5.0 and a battery that lasts years. Buy the Microsoft Bluetooth Ergonomic Mouse if you work long hours at a desk and want a sculpted shape with a thumb rest and five buttons. The Dell is the more portable and flexible of the two; the Microsoft is the more comfortable for all-day use. Owners of the Dell rate it well for reliability and battery life, while the Microsoft's ergonomic shape draws praise from people with wrist strain.

• Choose the Dell MS3320W if you need one mouse that travels, pairs over Bluetooth or a USB receiver, and rarely needs a new battery.
• Choose the Microsoft Bluetooth Ergonomic Mouse if you want a contoured right-hand shape with a thumb rest and extra programmable buttons for desk work.
