I am one of those people who just dislike the Mighty Mouse. I can't stand the single click nature of it where you have to lift your left finger up in order to right click. I am also really tired of blowing compressed air into the scroll ball on my wired Mighty Mouse when it jams up every 2 weeks. So I read a few good reviews of the Rocketfish Bluetooth mouse and since it was on sale I figured why not. First of all this mouse was clearly developed with the Mac in mind. The outside of the package says "for iMac/PC". However the instruction book inside the package calls it an "Apple Bluetooth Mouse". And it certainly is Mac like. It looks very much like a wireless MM but it is quite a bit taller and features a scroll wheel instead of the ball. The fit in my hand is more comfortable than the MM. I love the fact that it has a scroll wheel, and it gives a satisfying click on each roll. If you like the silent/smooth Microsoft scroll wheel style then this is not for you. It is more like the Logitech click click click scroll wheel style, and that is what I prefer. Another awesome thing about the scroll wheel is that it supports left and right scrolling by tilting the wheel in either direction. This too is engaged with a satisfying click in each direction. Finally the third button achieved by pressing the mouse wheel down again clicks very well and works great. Interesting the left and right mouse buttons are a more subdued type of click that is also really nice. Tracking has been excellent, much better than the wireless MM this replaced. For $35 on sale right now this is a steal. My only complaint is that the battery meter in the Bluetooth preferences does not work at all, I guess that was a MM feature. Regardless this is a terrific option for Mac users and is highly recommended.
