Dell MS3320W Mobile Wireless Mouse vs Lenovo Go Wireless Vertical Mouse

Buy the Dell MS3320W if you want a light, simple mouse that pairs over Bluetooth to several devices and rarely needs a battery change. Buy the Lenovo Go Vertical if wrist or forearm strain is your main concern and you work at a desk all day. The Dell is the safer all-rounder and has far more owner feedback; the Lenovo's 45-degree grip and six buttons win on comfort and control, but it is heavier, single-device and has a shorter battery rating.

• Choose the Dell MS3320W if you want dual Bluetooth and 2.4 GHz pairing across multiple devices, a 65 g body and a battery rated to last years.
• Choose the Lenovo Go Wireless Vertical Mouse if you want a handshake-angle grip to ease wrist strain, plus three programmable side buttons and on-the-fly DPI switching.
