Query: great bluetooth mouse

Even after 2 years, I found the touchpad on my laptop clumsy and inexact to use, and missed using a conventional mouse. Trouble is, I don't have unlimited USB ports, and hated clogging one up with a corded mouse, or the transmitter for a cordless one. So I tried this bluetooth mouse, got it paired with my machine (easy, fast AND only have to do it ONCE...thereafter, it REMEMBERS!) and now I am completely satisfied! No cords, no USB, and both right and left click buttons, as well as scrolling capability in an optical tracking (usable on any surface) mouse. The other "pearl" feature is the on/off button on the bottom, which conserves battery life of the device: when I turn off the laptop, I turn off the mouse, and so far have not had to replace the battery!So, 5 stars for it's comfortable feel, ease of use, and freedom from cords! I recommend this highly.
