What reviewers say

Reviewers praise the comfortable sculpted shape, precise tracking and useful dual scroll wheels for office work. RTINGS found it bulky for travel and unsuitable for small hands; Tom's Guide disliked the tiny stacked thumb buttons and found the notched scroll mode too loose. TechSpot found the feet slightly sticky on a cloth pad.
