Summary: This is a very high quality keyboard with excellent feel to the keys. The layout of the keys is great and easy to get used to. I am a lefty, so having the nice scroll wheel and mouse buttons on the left side pleases me a lot. The track ball works great as well. And it is wireless!
Ignore the negative criticism! This is a superior product.

Summary: The new Adesso WKB3000U is a major improvement over the Adesso WKB3000 it replaces. It is significantly lighter (by 8 ounces) and slimmer, and more responsive, especially the laser trackball. I put off buying this KB for a year because of all the horrors stories.
Summary: Got this to use in my classroom, the trackball did not work. I was replacing an older Adesso keyboard that worked for 7 years. :-( I am happy to report I found a great keyboard by Logitech with a touch pad that is working well on all 3 computers I tried it with AND has a great price.
Summary: I researched all the keyboards, spent a little extra and purchased the Adesso. I never heard of this company before now, but I am extremely pleased with the keyboard. I use a trackball on all my desktops so the trackball was a must. I use the keyboard in my living room for my entertainment center.
Summary: I was looking for a compact keyboard with track ball for use with home theatre PC and my shop CNC mills. Out of 5 different brands and models I tried out, this was my top pick. The track ball is of a higher quality than all the other units I tried out.
Good little device, just not as good as the prior version.

Summary: While this is a great little device, it isn't as good as the prior version. Unfortunately, that version (WKB-300UB) has been discontinued and is nowhere to be found. I still have my old model and beats me why they changed it.
