I am selling my Mini USB Optical Logitech Mouse for P400. Bought this at P550 3 weeks ago. I lost the receipt already. This is in very good condition and has been used just once. No hidden deffects its just that its small for me and i replaced it with a bigger mouse. Non negotiable. Good for laptops but if you want to use it for desktop its ok too.
