"A disposable, dual-mode mouse for when 'it works' is the only requirement."
The 'Dual Mode' feature allows you to pair the mouse with one device via its USB dongle and a second via Bluetooth, but you can only control one device at a time by manually switching modes.
This is a justifiable purchase for a travel bag, a secondary machine, or as a temporary replacement. Its value is in its disposably low price, rechargeable battery, and versatile connectivity for non-critical tasks.
Anyone using a mouse for professional work, gaming, or any task requiring precision should avoid this. The unstated sensor performance, suspect ergonomics, and questionable longevity make it a poor choice for a primary pointing device.
