Summary: There's a lot to like about this keyboard. The layout and waviness make is an easy touch-typer. However, the keys get sticky, and sometimes they need a lot of pressure to activate. This is REALLY irritating and mars what should be a top-notch product. The extra keys on the mouse are very handy for forward and backward in the browser history. I use them constantly and miss them when they're missing.
Summary: I bought two of these 2 years ago - one for work and one for home. I have given both a hard workout as I am a heavy pounder, and 8 hours a day minimum. The keys began to get sticky on both after about a year. I did the re-lube recommended widely on the internet - pried off keys, cleaned with swabs, used a dry spray lube and put it all back together. The keys continue to stick and make me want to throw the keyboard in the trash.
Summary: I've had this keyboard for a couple years now, and the keys have become much louder and certain keys are increasingly difficult to press, which sort of defeats the purpose of such a cool, ergonomic keyboard and significantly lowers my typing speed and accuracy. Otherwise, I agree with most of the other reviews in regards to how this keyboard will perform when you FIRST get it. At that point, it's great. It's just not built to last.
Summary: I own this keyboard in the CORDLESS version. I love it so much I bought a second one for my office. I was happy to find this low price for the keyboard! HOWEVER....If you look in the "Technical Details" of the Amazon listing, it says that this is cordless. IT IS NOT. The cordless version apparently only comes as a keyboard-mouse combo and costs about $20 more. Thats why I am only giving it 3 stars.
Summary: Overall, this is a pretty decent keyboard. Very light in weight. The keys are responsive. I've experienced no problems, thus far, after a month of solid use. My OS is Win XP Home Edition SP2 and all of the features are operable. However, it's baffling that an F-lock key is not on this design. NONE of the F-keys open/launch without holding down the Fn key. This is certainly an inconvenience as it requires using both hands at times.
Summary: It is great for crooked fingers from arthritis...easy to use my only problem is I ordered the new one...not refurbished...beware when ordering this Had a hard time with the customer service... they said they hadn't any new ones left and they do...The one I received is used... old batteries in the keyboard...marked and scraped without any paperwork what so ever...Came in a plain white box...not from the manufacturer... I wouldn't mind if I had ordered used..New...
Summary: Purchased this keyboard to use with my Mac setup as I knew it was compatible, and I wanted a keyboard with its very own wristpad. I was also intrigued with the "wave" affect of the keys themselves. This keyboard was certainly an upgrade from the Dell provided keyboard I had been using. My thumb was placed in a natural and comfortable position due to the provided wristpad which allowed me to strike the space bar with ease and grace.
Summary: I really like the comfortable built-in palm rest and the curved contour of the keyboard layout. But the other stuff I'm not too fond of. If the keyboard were cheaper, I could overlook it, but as it is, I have mixed feelings. F1 through F12 have custom functions assigned to them (eg F1 opens Microsoft Word) but you need to hold down Logitech's "Fn" key or else it will act as a regular F1.
