Doing that at a decently low current draw requires custom hardware, though, and the A4 Tech mouse A4Tech RFW-25 Mouse ain't got it; it's using something pretty close to a plain old corded-mouse sensor rig, as far as I can see.

So you've got to press a button. This applies even when the mouse is plugged into its charge lead, and so doesn't need to save power any more. It does it anyway.

So you can plug the receiver into a hidden server, if you like, and it'll always boot without complaining about a missing mouse or keyboard. The keyboard, like every other cordless model I've seen, saves power by not having any LEDs of its own. The radio system's useful range depends on your local radio environment, the position and alignment of the receiver and transmitters, and how close the receiver is to your computer. With the receiver a few feet from A4Tech RFW-25 Mouse computer, mouse control went flaky about 2.

The keyboard was OK up to maybe four or five metres, depending on alignment and intervening objects. Your mileage may vary. The radio system this kit uses has an "ID code" feature, which lets you use a button on the receiver to bind only one keyboard and mouse to one receiver, regardless of which of the two switch-selectable channels you've chosen for each device. So you should be able to have an office full of these things without interference problems. I didn't have another kit handy to see whether this feature actually worked, though, and it won't work at all if you haven't installed the supporting software.

One thing I did notice is that at one point the mouse pointer became erratic for about one second every time I pressed a key on the keyboard. It still moved in basically the right direction, but it did so slowly and unevenly. Basically, it couldn't be used until that second had elapsed. This was really annoying. Even for ordinary desktop tasks, it's a pain; normal users A4Tech RFW-25 Mouse want to move the mouse right after pressing a key.

For fancier tasks like selecting icons with Control held down to add A4Tech RFW-25 Mouse to the existing selectionit's really bad - when a key's held down, the mouse is constantly erratic. For Photoshop work, it's a freakin' nightmare.


And then the problem went away. I don't know why. I'd been fooling with the ID Connect button and the channel assignment switches constantly, and nothing had helped. Then, a while after making another change that hadn't helped, the thing just came good, and mouse and keyboard worked together in a perfectly acceptable fashion again. This problem might A4Tech RFW-25 Mouse had to do with radio interference from something else, I suppose; I'm flummoxed. It didn't recur. Beats me what it was. Apparently, the A4 distributors here in Australia will have stock of it towards the end of June.


It's a normal opto-mechanical ball unit, without rechargeable batteries. It needs less power than the KBSRP mouse, though, A4Tech RFW-25 Mouse it's not running high power DSP gear and an illuminator LED; this also means that it doesn't need a button press to wake A4Tech RFW-25 Mouse up after a couple of minutes. If the batteries aren't flat, this mouse is always ready to go. Click the picture at the right for a horizontal, pixel-wide version. The RFW looks as if it has a side thumb button for a right-handed person's thumb, anywaybut it doesn't.

It's got a side panel that looks like a button and can be pushed in a bit, but there's no A4Tech RFW-25 Mouse on the other side of it. One of the two scroll wheels is clickable, the other one isn't. So this mouse is actually only one wheel up on the normal wheelie-mouse control complement.

You get a couple of AAA alkalines with the mouse. They look like Duracells, A4Tech RFW-25 Mouse they aren't, in the great tradition of Taiwanese pack-in batteries. There's no ID code button; you can only use a couple of these mouses within range of each other. This mouse has the same roughly 90Hz sample rate as the optical A4 Tech, which is good. It's also pretty hard to freak out by moving it too fast, though it's still possible. The RFW is considerably heavier than the optical mouse, though; it's larger, and the ball's weight is significant too.

So I still wouldn't want to use it for twitch games, even when its ball A4Tech RFW-25 Mouse rollers were new and clean and pristine. I'm just a wimp who's been spoiled by optical mouses, though. Lots of people don't mind a heavier mouse. Power consumption When C'T Magazine tested wireless mouses, the A4 Tech offerings consumed less power than the competition, A4Tech RFW-25 Mouse is something A4 seem rather happy about; they proudly trumpet the mouse's 6.


The mouse that comes in the box is quite different, and consumes a lot more power. This isn't terribly important, of course, because you can just charge the A4Tech RFW-25 Mouse as needed.
