I just tried to search this site for reviews but the search functiion is disabled so... I think I need a new mouse, my 5 or 6 year old boomslang is not really going smooth anymore. It should be optical, so I dont have to clean it every once in a week. I just looked at offers on amazon.de and at first glance i wanted to go with a logitech mx510 or 518, but I think paying 50 € for a mouse is a joke. but they have a neat diamondback for around 33 €. is that good?
