This unit will deliver silky smooth operation consistently if you follow these tips.

1. Don't forget to hit a key twice (recommend SHIFT) to wake it up.

2. If you are dropping keys or have choppy mouse movements:
A. Try swapping with known good batteries.
B. Reposition the USB adapter. I got much better range by using an USB extension cable to relocate the adapter. Just moving the adapter six inches away from the computer case made all the difference. It eliminated keyboard dead zones.
C. Avoid wireless conflicts between the keyboard and wireless router by locking your router to a different wireless channel. Try channel 11. I found lower channels would conflict with the unit. Conflict issue is indicated by choppy mouse movements coinciding with wireless activity. Possibly wireless phones or microwaves could interfere too.
D. Switch wireless router's operating modes away from 802.11b. Try 802.11g-only or 802.11n-only if possible. I was able to more channels wireless router channels when I changed modes.
E. If shortcut keys ( Alt-<key> ) aren't working, it's because num-lock is on. I prefer to set the BIOS to turn off num-lock when booting.
F. 802.11 wireless activity will interfere with operation. Look for ways to reduce 802.11 activity.
G. Best to have a clear line of sight between keyboard and USB adapter. A couch's back or a body can greatly weaken the signal.

3. If the unit is dead, you may have accidentally pushed the USB adapter's tiny "sw" button. It's used to pair with your keyboard. Re-pair by pushing sw again and pressing keyboard's FN key within 15 seconds.

Thanks to the myriad of reviews, product works exactly as expected. Yes, it works well with Vista without drivers.

Got this for my home theater pc. It works great! Range is about 10 feet or so.

For all those reviewers complaining about the auto power off and no on/off switch. To wake up the keyboard, HIT THE ENTER KEY TWICE!!!!!! You DO NOT need to take out the batteries. This is documented in the product lit, just not very well - hence the 4 stars.

I had been looking for a wireless keyboard with a built-in mouse or touchpad to use with my Mac Mini. Another reviewer said he/she had used this keyboard with great success with a Mac Mini so I decided to buy it. My computer is set up upstairs and I wanted to be able to control it from downstairs so I could surf the net, write letters, etc., using my LCD projector and 100" inch screen downstairs.

I plugged in the USB dongle, put the batteries in the keyboard and then powered on my Mac. Setup was unbelievably simple. I read the Adesso instructions for setting up the keyboard but that was not necessary. The Mac recognized that a new keyboard was plugged in and just asked the normal setup questions of hitting the key to the left and key to the right of the shift key so it would know what type of keyboard it is dealing with and I was off and running.

The keyboard works flawlessly. Within 5 minutes, I was operating my iTunes from downstairs and checking my e-mail on the big screen. What a sweet set up.

An added bonus is that this does not interfere with my Apple bluetooth keyboard that I use on my desk with the Mac. I can switch back and forth between the Adesso and the Apple bluetooth keyboards seamlessly.

For what I want to do, this keyboard is perfect.

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. Unfortunately, it sometimes, and often enough to be annoying but not enough to be unusable, stops responding. Missing a keystoke or two, or not responding to your touch on the pad. A second later it will start acting normal.

I have this behavior even with 100% fresh batteries, and I'm not mistaking it for the auto-sleep function. I mean, you'll be typing, and it will stop responding for a few seconds.

Perhaps this is a wireless issue; it does use the crowded 2.4ghz band and I live in an apartment and run a wireless network. Then again, I figure that's true of many people who would buy this product...so it'd be nice if they could design around those impediments.

I suppose it's also possible I have a defective keyboard, but enough people have commented on this as a problem that I suspect it's just the design.

So. Works pretty well, but I'll have my eye out for any new products in this vein...


I contacted Adesso about my problems and they suggested that I return the keyboard under warranty. Doing so was fairly painless, it took a week out and a week back (UPS ground, I pay to get it to them). But: new keyboard still has the problem of intermittent response. It seems to me that having it on my lap or on a flat surface like my ottoman blocks the transmitting antenna; it seems to work fine if I hold it with just one hand and type with the other--but that's not a very usable operating position...
