What this mouse does

The DELL MS355 is a wireless optical mouse that connects through a USB receiver or Bluetooth. It offers a 4020 dpi sensor and three buttons in an ambidextrous black shell. Office workers and mobile users who need a simple, cord-free pointing device will find it fits the task.

How it handles daily use

The optical sensor tracks at up to 4020 dpi on most desk surfaces without a pad. A 2.40 GHz radio link keeps the cursor responsive during long documents or web sessions, while Bluetooth gives a second way to pair when a USB port is not free. Power comes from standard batteries that are not included.

What to verify before ordering

Check that your computer has either a free USB-A port for the 2.40 GHz dongle or built-in Bluetooth support. The mouse is ambidextrous, so left-handed use is possible, but there are only three buttons and no programmable extras. No software installation is required for basic operation.

Questions about this item

Does the optical sensor draw enough power to shorten battery life during all-day use?

The optical sensor runs at 4020 dpi with no extra power specification, so typical office use will not drain batteries unusually fast.

Must my computer have both a free USB port and Bluetooth to use this mouse?

You can connect either through the 2.40 GHz USB receiver or directly via Bluetooth, so only one of those interfaces is required.

Will the ambidextrous shape feel comfortable if I keep using my older right-handed mouse alongside it?

The symmetrical design and three-button layout work for either hand, letting you switch between mice without relearning button positions.
