Great Keyboard Mouse Worse than Useless

To my horror the mouse turned out to be an ancient ball mouse. Why on earth would anyone combine cordless technology with proven skip jump jam judder is beyond me. HOWEVER I accept it is entirely my fault for not checking the small print of the specification. Unfortunately for me I did not follow my initial instinct and send the whole lot back. I persevered on the basis of it must have improved by now ? Wrong! Within a month I had further invested in an upmarket mat and finally in a new bin liner in which to deposit said mouse. Within two weeks it was requiring twice daily cleaning regimes. None of which appeared to achieve much for longer than half an hour. After six weeks I have finally given up and thrown the lot in the bin. I am now ordering a replacement optical equivalent. Do not get caught like I was. The keyboard was fine no problems, but the mouse is the most useless pile of junk I have come across in 15 years.
