I got one of these as a replacement for a Kensington Pocket Mouse. Right away I liked the absence of the "tail" and the freedom that gave me. I also liked the more solid, heavier feel (you can adjust the weight by putting in either one or two batteries).
There are no actual left and right buttons. Instead, there's a sort of rocker switch in the base which activates when you press the top of the mouse shell where the buttons ought to be. This takes a bit of getting used to. In particular, you need to avoid resting your hand too heavily on the mouse, which prevents it from rocking correctly.
The multi-directional scroll ball has a very light feel to it - you literally just need to brush it wish your fingertip. It feels fragile and it is: after 5 months of light but daily use the upward scroll function has now become intermittent. Another problem is the button function of the scroll ball. The ball is so delicate that pressing the button to click it invariably means you move the position of the ball slightly, which is annoying if you're trying to click on an item in a list.
The fourth button is built into the finger rests on the side of the mouse. You need to use a lot of pressure to activate it, squeezing the mouse as if you're trying to throttle the life out of it. I guess that's so you don't keep pressing it accidentally while you're mousing, but the difficulty of operating it limits its value for me.
Battery use is reasonable (about 2 months with both batteries installed) but only if you use alkali non-rechargeables. I've tried two types of rechargeable batteries, but I only get about a week's use before the "low battery" warning comes up. When I do replace the batteries the mouse doesn't always link up with my Mac, so I have to use my old USB mouse in order to navigate to the Bluetooth menu and re-establish the connection.
The software that comes with it allows you to set up some basic functions for the buttons, but if you want to program different functions for different applications, you'll need to install the shareware application SteerMouse. Unfortunately the excellent (and free) Kensington MouseWorks is not compatible with Mighty Mouse.
