Summary: bought this model after reading all the user reviews on nearly every wireless model that newegg listed for sale. my last adesso keyboard died prematurely as well. i should have learned something from that. now i gotta get an rma and pay for shipping to send this defective unit back? i gotta be nuts!
Pros: Decent weight for a wireless mini trackball keyboard. Keys have good resistance when typing. worked in range with my htpc
Cons: trackball fits loosely in its socket and has sloppy action. you can hear the trackball and the batteries bang around in their housing when you pick it up quick. biggest reason for 1 egg is that the keyboard has issues right out of the box with one section of the keyboard nonfunctional, ie; comple...
Excerpt: This product works as advertised. I have three within a short distance of each other and they do not interfere with each other. The only issue I had was that the space bar would stick on one unit. I snapped the bar off and slightly sanded down two plastic "guides" and then replaced the bar.
Excerpt: The keyboard sets up very easy, but once connected without some kind of feedback system you can't tell if its on, or num-lock, or caps is on. Additionaly, the track ball is so fast it is hard to make small moves on screen.
Summary: It up and died yesterday. I went with a Logitech k400 this time. Maybe it will last a bit longer. I would have given it 5 stars if it had not died.
Pros: Worked great. It does what it needs to to work a HTPC or any other computer. Not a great keyboard for writing letters or other heavy keyboard use. Windows 7 recognized it right away on the first bootup of a new build.
Cons: Difficult to clean out trackball. It has a lot of screws that need to come out and some un snapping to clean out the track ball when it gets lint filled.
Summary: It you're looking for the range needed for an HTPC (home theater PC), nothing is more frustrating than having to get up or finagle the device closer to get it to work.
Pros: Trackball and mouse buttons are in great positions for use.
Cons: The radio in this device has a range of only several feet. I've owned three different units and sent one out with an htpc I've build for a friend. One I returned for replacement b/c I thought the radio was broken. It turns out the range is no more than about 5 feet reliably with the receiving usb...
