Quote from the review at ExtremeTek:
“When in search of the ideal mouse one often seeks innovation, functionality, comfort and style. This is what led me to the Microsoft Wireless Intellimouse Explorer, a practical and yet intriguing mouse for the average user seeking an above average mouse. With this model they claim to offer longer battery life, revolutionary tilt wheel technology (for side-to-side scrolling), five programmable buttons, and an ergonomic design. It all sounds great, but is it as amazing as they say?
