The tracking is highly precise, nearly matching the performance of my Logitech G305, even when comparing pixel-by-pixel movements at the same DPI (though the G305 might have a slight edge, possibly due to a placebo effect). The mouse is as lightweight as advertised. A Reddit-found, author-less software allows for 1000Hz polling rate, key customization, and RGB control, though I'm hesitant to recommend it. The middle mouse wheel has a good feel. The plastic build quality is satisfactory. The DPI change button feels cheap, but I rarely use it. The primary buttons require a significant amount of force to press. The power switch on the bottom is loose and makes a rattling sound.
