The colors are flashy as shown. This mouse is light, its handling is nice. The included battery allows for immediate startup. Recognition Windows 8 is instantaneous and requires no specific driver. Note however that software (SetPoint) is available on the Logitech website to access extended settings and information (including the battery charge). One star less for plastic packaging and especially the completely useless paper manual and warranty. To reduce waste, energy and pollution, why not just a flashcode pointing to the electronic version of these documents?
