Dell wm 123 optical mouse is really bad experience for me. It is wireless but it didnot work as I expected.there is no dpi setting so mouse sensitivity is really bad and it was not controlled.when I was playing Counter Strike game it did not work properly and it was really bad experience for me.
Now I told its scroll button, scroll button did not work after 2-3 weeks after bought .Right click did not work when I was playing cs 1.6.and Click is very slow if we compare to other optical mouse.its blooth device is also very slow.and it only catch within 4-5 ft .I don’t refer to anyone to buy this mouse.
