"A functional, disposable mouse priced appropriately for its minimal-cost components."
The '7200 DPI' setting allows the cursor to move very fast, but it doesn't mean the mouse is more accurate. It's a budget optical sensor digitally boosted, making it suitable for browsing but not for tasks requiring pixel-perfect control.
This makes sense as an emergency backup, for a public-use PC, or if you need a mouse for less than $15 that has forward/back buttons. It is a temporary tool, priced as such.
Anyone seeking a primary mouse for daily work or any level of gaming should invest more. The unspecified sensor and switches are not engineered for performance, reliability, or longevity.
