This wireless mouse is PERFECT! The pros: - Small size - Its colors (I have blue, red, gray) - Its accuracy - Its quality - Its price The -: - Sometimes the mouse "disconnects" the PC but usually it comes from the USB socket of the PC (on extension for example) and not the mouse. it is sufficient in this case to disconnect / reconnect. Conclusion: highly recommended. Cheap and very reliable (I just ordered my third date, for my job)
