I absolutely loved loved loved this keyboard when I first purchased it…FIRST purchased it. I type for at least 6-7 hours a day (medical transcription) and I loved how the keys felt and the 10-key pad was awesome. However, literally three months after purchase it became very temperamental with battery life and not having enough light and so on and so forth. Five months into using the keyboard, it just stopped working one day….won't take a charge, nothing! Yes, now I am out $60!! I did not return this through Apple, as I purchased it directly through Logitech and I am just too busy to sit on hold with Logitech for who knows how long over $60. Soooooo…..I am still on the hunt for the ever-elusive "perfect" keyboard! My apple wireless keyboard is awesome, but no 10-key..
