My Wireless PC Gadgets

I got wireless 2 mouse (or mice?), for my laptops. One is smaller, and the other is bigger, but both of them functions the same. They both work with triple A batteries (small one) and double A batteries (bigger one). Logitech is bigger and bulkier but batteries can last longer. While Gigaware (small one) consumes batteries faster because it doesn't turn itself off when not in use. You have to manually turn it off, which I don't do because I always forget to do it :)
They are very convenient to use because you don't need to have those wires anymore. Makes your space clutter free. Ideal for a traveller like me too :)
