Logitech M305 Wireless Mouse - 2.4GHz USB Receiver, 1000 DPI, 12-Month Battery Life, Ergonomic Design (Blue) - Ideal for Laptops, Desktops, Office & Home Use

So far, I've been extremely happy with my choice of this mouse. Superficially, I enjoy the color and love the individuality of a teal mouse. Setting up the mouse was unbelievably easy (plug in the tiny USB and it pretty much sets itself up within 5-10 seconds). The USB plug is small enough that I just leave it in my computer at all times, as I don't have to worry about it catching on things, losing it, or forgetting it that way. The mouse fits my hand nicely and is comfortable to use for extended periods of time. It's much more sensitive and reacts better than other wireless mice I've had in the past. I've had the mouse for about two months and have used it every time I use my computer (I shut the mouse off when my computer is off) and I haven't had to change the batteries at all, so at least it doesn't seem to suck batteries like some other mice do. The mouse has worked well on multiple surfaces too. I would most certainly recommend this mouse to a friend for its reasonable price, general aesthetics, and functionality.
