A very nice product in my opinion. Hello friends I am Saurabh. I am reviewing a product which I like that is dell wireless wm123 mouse. It is energy efficient mouse because a single pencil torch battery work for at least three months on an average use. I am in favour of buying it as it has three nice feature. First one is obviously it’s efficiency. Second one is it’s softness so that we can scroll and click without giving pain to fingers. Third one is it’s port where we can place its wireless USB. It also work with tablet and phone on attaching it with OTG Cable. Also it works well with laptop of any model or operating system.
