"An aggressively priced ergonomic mouse with specifications that defy its cost and credibility."
The '5-Level 2400 DPI' means you can press a button to cycle through five sensitivity settings, useful for switching between fast cursor movement and slower, more precise tasks. It's a real feature, but doesn't imply a high-performance sensor.
This is for someone needing a cheap, temporary, or secondary wireless mouse who values a slightly more ergonomic shape over build quality. Its price makes it a low-risk purchase for a travel bag or as a backup.
Mac users who rely on side buttons for navigation should avoid this completely. Anyone seeking long-term reliability should also skip it, as the claimed durability is not credible at this price point.
