I am not keen on using the mouse pad on laptops and much prefer a mouse

I used a really cheap wireless mouse [ £4.99 ] which lasted about 2 years and was brilliant [ unfortunately never seen them for sale since ]

since then I have been unable to find anything as good and reliable as they are often erratic [ currently using a Microsoft ones which more than 50% of the time drives me nuts

the usb connection has to be as small as possible to prevent possible damage to the connection or usb port

any suggestions for a really good reliable wireless mouse
