"Sixty disposable mice for the price of one decent one; a purely logistical purchase."
The '1000 DPI 3 Button' spec translates to a basic office mouse. It will move the cursor predictably for web browsing and email, but will feel imprecise for anything more demanding like photo editing or gaming.
This is a rational purchase for IT departments, schools, or conference organizers who need to equip a large number of stations for the lowest possible cost. The value is in the quantity, not the quality, treating each mouse as a consumable.
Any individual looking for a mouse for their personal computer. The poor build quality and generic ergonomics make it a frustrating primary device. A single $20 mouse from a known brand is a far better long-term investment.
