ADESSO 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

En remplacement d’un version avec fil. Seul bémol est l’aimant pour ranger le dongle qui est un peu faible.

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

Update: DO NOT BUY THIS! Used it for a year, should have returned it on day one. From the get-go, I noted odd behavior in the keyboard (like the FN key randomly switching on, or some keys not working correctly). First I thought it was just due to low battery, but now I realize its just poor product design. Now, a year later, the keyboard now has several keys that do not work, primarily the ctrl and F5. Additionally, the FN key does not seem to do anything (like it used to be that FN+k=9, now its just "k"). The track-wheel became wayy too sensitive, and is basically not usable. Only thing that I admit is nice, is normal typing on it. Really wish I could say more. ==================== Overall its good. However on low battery it acts weird. And if it is slightly too far from reciever it losses connection

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.

My favorite keyboard! I bought it because it uses an rf link instead of bluetooth. This is important to me because a bluetooth link is not connected until the OS is loaded so it is not active during the boot up. Since I have several OS systems installed, they are selected during boot, and an rf link allows me to select my OS whereas a bluetooth link does not. The only negative for me is that it allows letter keys to act as an number keypad. Still its a great keyboard and I bought 2, one for each of my machines. I recommend it, if you need to make selections during boot, and you want to be able to access you bios.
