8Selling an HP vertical mouse with a minor functional flaw in the scroll wheel (scrolling up or down pages becomes difficult and erratic—sometimes it moves 1 page, sometimes 4 or 5 pages) and the DPI button does not work, though DPI can still be adjusted via HP's software. The mouse is extremely comfortable—I've tried several vertical mice, and this one is undoubtedly the most comfortable. However, since I rely heavily on scrolling for technical drawing, I unfortunately had to purchase another mouse. A new mouse costs approximately €100–€120. Due to the scroll and DPI button defects, the price is lower. The mouse comes with its original packaging and all components. Hand delivery available in the Lisbon area, or shipping at buyer's expense. Feel free to ask any questions.
