had no problems installing the glorious software and the rgb is nice but i dont care much about it double clicking on it works perfectly normal goes to max 4ms on the debounce time the side buttons do feel a little bit worse than the viper mini but their decent built quality is alright i dont agree with the price 60 euros as of making this review and its better off being cheaper the media could not be loaded

although the viper mini is a little bit taller i dont really mind that the model o is shorter as i can still grip the mouse well

decided not to get the regular sized model o as i feared that since my hand was very comfortable gripping the viper mini i dont think my it would be comfortable with the regular model o and im glad i got the smaller one as its a perfect size for me

Decided to buy this as a replacement for my razer viper mini
