Brand New Wireless mouse and Keyboard

I just bought a new Logitec 's wireless mouse + keyboard.I have planned to change it long time ago,but just don't have the time to buy it at the same time couldn't be bothered about this thing.

My mouse have already spoiled,the scroll bar cannot function anymore.I was using this old keyboard for 5 years .

So, i feel like changing a new one!!I wanted a wireless keyboard all the while.

◦Can put wherever i want
◦No wires.Won't be so messy.
