[M] CHERRY MW8 Advanced Wireless Mouse Review
 

The MW8 Advanced mouse is a good choice to be picked up while on trips along with your favorite laptop thanks to its long lasting battery and premium build. If you have all USB ports occupied, you can always use the product on wireless since all laptops now do incorporate BT interfaces as well. Compared to the previously tested CHERRY mice, this one houses a much better PixArt sensor that is able to track on all surfaces, including glass and its DPI can be adjusted in four different steps, in order to cover more usage environments: 600, 1000, 1600 and 3200 DPI.
