"It costs less than a fancy coffee and works exactly as you'd expect."
The '800 dpi sensitivity' means your cursor travels less distance on screen for every inch you move the mouse; on a modern 1440p or 4K monitor, this will require noticeably more physical hand movement to get from one side to the other.
This is a rational choice for bulk IT deployments, as an emergency replacement, or as a backup mouse to keep in a laptop bag. The tilt-wheel gives it a slight edge for spreadsheet work if the budget is near-zero.
Anyone using a monitor with a resolution above 1080p will find the cursor movement frustratingly slow. If you spend hours a day using a mouse, the lack of ergonomic shaping is a valid reason to invest more.
