It feels very plastic in its motion and just seems like it was made using the cheapest materials possible. The cheapest feel to this mouse is with the scroll wheel. The thumb buttons feel naturally accessible and have a good surface to grip too.
It feels solid, is a good weight for me, has a smooth action and fits comfortably in my big hand. The Gigabyte mouse is one of the better quality, wired mice i have used over the years and is excellent value for money. I initially purchased this mouse as a direct replacement for my Logitech MX Revolution mouse as it had failed on me.
Easily one of the best in its price range.
