Summary: My wife wanted a smooth mouse for her fingers to roll on. After receiving it we were very disappointed with the product. It is all plastic and very light weight (which is great if that is what you're looking for - we actually wanted a metal mouse area) The range, with brand new AA batteries was good if the USB key was in the front of the computer otherwise it barley worked. I'm thankful that this company took it back without any questions asked.
Summary: Was looking for an All-In-One keyboard-trackpad to help our Admin. This looked like a great fit as it was similar in style to her home laptop and got good reviews on other sites regarding compatibility with Windows and Mac. To make a very LONG story short, 2 of the 3 that I received functioned properly for approximately 2-3 hours (the first one, the trackpad stopped functioning, and the third stopped typing capital letters), and the other one arrived with food bits...
Summary: This keyboard works as expected. Nothing fancy. It's the closest thing to a wireless version of a full laptop-style keyboard that I've seen. The range is fine. It's compact and light. However, there are a few problems. There's no software for the touch pad and therefore no way to adjust it's sensitivity beyond your generic pc mouse control settings. It's kind of sluggish. The keyboard layout is not as pictured above. It is more like the 4000UB.
Summary: Battery life not the best, 2 weeks, 4 AAA batteries down the drain, it gets expensive. Keyboard is hit or miss, keys stick, double take, keys pop off. touch pad over sensitive and track slide is not placed in the most user friendly position. Wireless is pretty much line of sight, set a drink or a book in front of this keyboard and it will not communicate with receiver. Very compact design, great for web surfing from your easy chair. Just be aware of the drawbacks.
Summary: This keyboard is good as far as the distance it picks up and you don't have to point the keyboard toward your computer for it to work. However you will be typing, as I am now and the cursur will jump back to the beginning of the line. The other day the letters got off set, meaning I would type a N and a B would show up. So I had to reset the computer for the keyboard to reset as well.
Summary: I think this is probably the best product amongst wireless keyboards you might use with a living room PC, though the only other I've tried is the Microsoft Remote Keyboard for Media Center. The problem with that keyboard is its awful pointing stick; though it does get more flexible with use, it's not nearly as good as the pointer sticks you find on IBM Thinkpads. This keyboard has good key feel, a built in pointing device, and is a nice size (about 8.5x11) for the couch.
