Is the RadioShack Ergonomic Wireless Mouse worth it?

It is a reasonable budget pick if you want a shaped wireless mouse with side buttons. Compare its price with Logitech and Amazon Basics mice in the same range before deciding.

What is 3,200 DPI enough for?

It is fine for office work, browsing and casual gaming on a normal monitor. Competitive players who use low in-game sensitivity often want 8,000 DPI or more.

Does it need a battery or charge by USB?

The listing does not specify a rechargeable battery, so plan on standard batteries. Check the box contents before buying.

Will it work with a Mac or a Chromebook?

A standard USB wireless receiver mouse usually works with Windows, macOS and ChromeOS. Confirm the connection type on the listing first.

When is the best time to buy it?

Budget mice see the deepest discounts during back-to-school and Black Friday sales. Use the price history to see whether the current price is above or below its usual level.
