TechPowerUp posted a review on the Roccat Kone Pure Owl-Eye
A quote from the article:
Roccat's Kone Pure Owl-Eye can be considered a revamped Kone Optical or Military, using an updated PixArt 3361 sensor and more compact dimensions. This $70 mouse is also lighter and delivers outstanding precision and tracking performance. The mouse wheel is probably the best we ever used, both for scrolling and clicking.Roccat Kone Pure Owl-Eye @ techPowerUp
