Customer Reviews:
LOVE IT!! 
I bought this keyboard about a year and a half ago for the office, let me tell you I feel in love with this thing. I had to buy one for home too. I love all of the extra buttons so you can skip right to your favortie web pages, documents and everything. I have only had to change my batteries once in each. Highly reccomend.
Great wireless — and for a Mac! 
Had some issues finding wireless keyboards for Macs. We tried using Microsoft’s PC version, but couldn’t get the shortcut keys to work. This new, Mac version works great. No problems at all.
Sluggish Mouse on Mac 
I have the receiver set up on a kvm switch for a PC and a Mac. The combo works great on the PC but the mouse is very sluggish on the Mac. I also get nfrequest “low wireless signal” message on the Mac (not on PC). All in all, too much of a hassle and I will be returning it.
A full featured keyboard and mouse, but a little quirky 
I am pretty happy with this wireless keyboard and mouse combination. The curved keyboard is comfortable. There plenty of dedicated keys. I am especially happy that it is a Mac specific, meaning you don’t need a sharpie to reassign ALT to CMD. The mouse tracks well, except on some surfaces, like marble - maybe not opaque enough?
Here are my two complaints about it:
1) On a Mac you need to sometimes hold down a key combination during startup. I had to read someone else’s review to learn that this is, indeed, possible. But, you have to do it just right. You have to watch the light on the little USB dongle and, when that light blinks right after your screen turns grey, you have to then press the key combination you want. The window of time is only about a second or two long. If you are zapping your PRAM and need to hold down CMD-OPT-P-R, then you might need to practice or try a couple times. Also, this is in contradiction with Apple’s instructions to press the buttons BEFORE the screen turns grey.
2) Placement of the USB dongle - that receives the RF signals from the keyboard and mouse, is a bit touchy. I have mine sitting directly behind my keyboard - practically touching - yet I still get this annoying message that says my RF signal is weak. I stopped the message, but still it misses some key clicks. It was worse on top of the desk. I am still messing with this after many months of use.
Battery life seems to be quite good - don’t think I have changed them yet. Setup is straight forward and most defaults work fine for me. I had a lot of trouble with Logitech keyboards, so this is a big improvement.
It works….. but 
This is a flat keyboard with the keys angled so that the wrists are not bent at odd angles to the body. (I wanted the split keyboard with the arch to allow the hands to fall naturally, but that model is not ‘keyed’ for Mac.)
This is a compromise and the improvement in comfort is slight compared to the Mac’s keyboard.
Most of the ‘Mac specific’ buttons actually do what they are supposed to. Exceptions: Zoom only magnifies text and only in some programs, where the Mac’s zoom magnifies the entire screen, I miss that feature. (Mac’s zoom is availed by pressing a combo of three keys, that combo does not achieve the zoom on this keyboard) I was not able to get the ‘expose’ button to work on this mouse, and even if it did, it is in an uncomfortable position. Other than that, the mouse is comfortably arranged.
The issues with signal strength that others are having are present in this keyboard and mouse. The most annoying part is the frequent window telling me the signal strength is low….etc, etc. From day one, I have never had more than two bars out of five worth of signal strength, regardless of how close the keyboard/mouse is. Even though the signal strength indicates ‘low’, the keyboard and mouse function fairly well.
The convenience of wireless is outweighed by the signal issues and lack of USB ports. Next time I spill the coffee on the keyboard, I will get a wired one and probably stick with Apple’s. Which reminds me, the software has to be installed before the keyboard is connected, and you need a keyboard to do that…. usually. Apple Care helped me around that.
Pros:
Keys arranged in a curve.
Padded palm rest
Extra keys to program in favorites
No wires
Cons:
Signal strength issues
Pop-up warning about signal strength
Inadequate zoom tool
One mouse button 99% useless for me
Silver colored plastic
No wires (it is a pro and a con)
