WKB-3100UB Wireless Mini Trackball Keyboard - Compact 87-Key Layout, Built-in 800 DPI Optical Trackball, 24GHz RF Wireless Technology, USB Interface, 30-Foot Range

Finally a wireless keyboard that is easy to navigate. My company issues this same keyboard but in a wired version. I love the keyboard but I go through a few every years because the cords will eventually short out. I tried a couple of wireless keyboards with glide pads but I found myself accidentally sliding folders into other folders--well that's a disaster waiting to happen. (It really comes downs to what you are use to, glide pads or trackballs.) If you are looking for a quality keyboard with a trackball controlled mouse, you will want to try this one. I've been using this same keyboard (wired version) for years and it holds up excellent. It lives in a hot car, gets dropped at customer sites, and gets plenty of use daily. One thing I'd like to see improved is a more secure storage slot for the receiver. The receiver is magnetic and just kind of sticks in a small recessed area on the back. You will have to be careful because it won't take much for it to fall out.

This model is unsupported by Adesso, and its manual no longer is listed on Adesso.com's site. This unit is broken - the Alt key is always-on, so the keyboard which sells for about 2X comparable models that lack a trackball is useless.

have only owned for a couple of weeks now. So far, so good. If feels rather sturdy. Button placement is fine, if you are used to wireless keyboards like this. Trackball operation is smooth, and doesn't feel like it will break anytime soon. I'm usually 20-30 feet away from my receiver, and haven't had any trouble with reception. If I had to list any minus's, it's that this keyboard is fairly bare bones. There is no scroll wheel, or trigger buttons, or anything like t hat. I'm rather used to not having those, so not to big of an issue. biggest plus is that this has a track ball, and not a track pad, like many of the newer keyboards. That's a big plus in my book. I've been trying to replace an older keyboard for my htpc (old one is 5+years old, and doesn't track as smoothly as it used to), and this is the first keyboard I've used that still felt like I'd get a lot of life out of it, after owning it for 2 weeks. If you are looking for a wireless keyboard with a track ball, this is just about your only option

I liked the size of the typewriter and all was working well but after a few months the trackball stopped responding properly even when you are near the receiver. After a few days it might work again and after some time it stops responding again. It looks like the camera or censors are not recognizing the movements of the ball above. Very frustrating and waste of money. I have to buy a different one.

I have had two of these Adesso wireless mini keyboards and have just ordered a third. I like them very much but I can only give 4 stars. The reason? The legs on the bottom will snap after about a year. Otherwise, the keyboard works perfectly and could have a long, long useful life. I need the slight elevation that the legs provide, however. Once they snap, there is no way to repair them, unless the manufacturer would be willing to send a new one. I probably should try that! Otherwise, very good product. Very compact. No 10-key panel so only about 14 inches wide. Keys are very response. I don't use the trackball so I can't make a judgment about that feature.

the keyboard has some weight to it it looks really nice too and is functioning just fine.

Keyboard and trackball worked great and had reassuring build quality for its price. The lack of a scrollwheel and NumLock indicator light were the only faults I found with the layout, and I didn't feel safe trying to remove the keycaps for regular cleaning. However, reception would randomly drop from even less than 5feet depending on the angle. And I'm not talking about any wide angles, the thing was really finicky about how it was oriented relative to the receiver. Speaking of the receiver, the length and build quality of the receiver is terrible. I had it plugged into the front panel of my HTPC (not rear to mitigate the reception issues) and it snapped in half when my cat bumped into it. Since it's not Bluetooth, RIP keyboard.

After 6 months of minimum use on my living room home theater system, the trackball has become unusable... erratic and extremely slow. It is used in a clean environment and the keyboard was never dropped or otherwise abused. After reading other reviews here and on other sites, I realize I wasted my money. Just as well as it's an ergonomically challenged keyboard anyway. It's clumsy and difficult to move around within living room seating area as there are no handles nor non-key space in order to grab it. And it requires two-hands to operate as there's no buttons on the right side, near the trackball.
