I am sick of all these cables and want to get rid of some of them by getting a wireless keyboard and mouse - printer too, eventually but not yet. Is there anything I need to consider, like security, brand name, or something else, like how well they work? Do they have any extra lag or some such?

Thanks for any input.

I quit using wireless for two reasons: batteries and signal.

Neither should be a concern but they both were. :P I guess I have some sort of weird gamma radiation that can screw with my reception if the weather is just right.

And as far as batteries, the better the device and the more you go through. Also, some companies (not all but some) put a warning light on their devices for low battery but it doesn't come on when the battery is dead, it comes on when the battery starts to lose power which pretty much happens right after you put it in, so you have this annoying light blinking all the time.

Never heard of above comments but wireless is no problem for me (microsoft).As for batteries,ever heard of rechargeable?

I don't mind buying or recharging batteries. I think I'll try it. Thanks to TinyE and Tauto

I'm a happy wireless user. I use a Logitech K350 for the last 5 years and I think I have changed the batteries only once. Standard AA. As for mouse, i use an Anywhere MX2, however for gaming probably other types might be better. I like the MX2 because it works literally on anything, I haven't used a mouse pad in the last 5 years (had an Anywhere MX but the batteries were getting expensive, a new set every month and a half). The MX2 has Li batteries, they last for about 3 weeks until charging, however under Linux the power reporting doesn't works so I do get out of juice unexpectedly sometimes. On Windows I don't know, haven't yet ran out of power while using the mouse under win. Of course you can charge it while using it, but I got so used to the light weight that when I plug it in, it's uncomfortable for gaming (twice so far have I ran out of juice during deatchmatch in Quake 3)
As for lag, it's inexistent.

I had a wireless keyboard and then I spilled tea on it and that was probably it.

Now I'm eyeing a keyboard that's 7 pounds of steel, plastic, and buckling springs.

I'm running a Logitech combo - actually running it x2, since we have two of each:

M705 mouse + K750 keyboard.

We have yet to replace batteries in the mice. Replaced the first mouse after 18-24 months (wife clicks the buttons like they owe her money), and reused its batteries elsewhere. I think Logitech say a pair of AAs is good for 3 years. For the keyboard, well, it's solar. Charges an onboard battery for use later in the dark. Again, no problems with losing power, even after 3-4 hours gaming in a dark room.

Range-wise, I have used the mouse a good 8 feet from the tower that has the receiver. No problem. When I game on the big screen with the laptop, it sits about 3-4 feet from the keyboard and mouse. Again, no problems with reception or lag.

From my experience, wireless has been problem-free.

>Security: it's possible to intercept each keyboard & mouse input wireless or not, wireless is much easier; but in most cases they (who?) will surely hack you computer ;)
>Brand name: whatever you like, i recommend Logitech (made in China) and dislike chineese brands (made in China as well)
>Something else: your keyboard and mouse ABSOLUTELY must have a possibility to recharge via USB/microUSB cable when needed; you should use build-in (not much choice here) accumulator or rechargable AA batteries, currently most produced are Li-OH types, meaning that in 2-3 years they will be wasted, most probably with you wireless devices (most common problem is mouse button disfunctioning); also if play online FPS games you might (or mught not) find it lagging a bit, mouse should have at least 1200 dpi (you might consider 3k or more dpi)

I had a few wireless keyboards and mice (sic!), and afrer a while i decided to roll back to my cable keyboard & mouse, because i hated how really fast my batteries got exhausted, i bought 20 rechargable AA batteries 2700mAh and it wasn't enough. But it was 2 years ago, something must have changed to the best since then.

I use the wireless Logitech M325 mouse and K360 keyboard quite often with my laptop. Some comments from me, also regarding some points others made:

- For me batteries haven't been a problem. They seem to last ages for these devices (months), but then my use is not quite daily.

- I haven't noticed any noticeable lag even in game use. Maybe if the laptop was very far (like 3 meters or more) from the mouse/keyboard, but only slightly.

- My mouse and keyboard use the Logitech Nano USB receiver, so they use only one USB port as they use the same receiver.

- I've been thinking of Bluetooth wireless mouse/keyboards as they wouldn't reserve any USB port... but I am unsure if there are any downsides? Lag? Interference? Eat batteries faster (like some people above complain)? Can you comfortably (or at all) use several Bluetooth devices at the same time?

- For a wireless mouse specifically, having to insert a battery into it tends to make the mouse bulkier in size, and also heavier. So a leaner/lighter wired mouse still feels slightly superior for high-speed action games and such. For wireless keyboards this is obviously not an issue.

All in all, I am quite happy with the Logitech wireless devices, but my main point to use them is with laptops, when I want freedom of how to use them, e.g. lying on the sofa two meters away from the laptop. I see less reason to use the wireless devices on a desktop environment, I don't see them bringing any big benefit there..

I use to be all wireless but it comes with so many annoying little issues that it just doesn't seem worth the hassle. Plus it is all cheaper wired anyway.

I totally suggest Logitech, if you're ok to pay more than usual.
My wireless mouse + keyboard have 8 years by now.
The KB can be recharded via its cable and the mouse via rechargeable batteries (and they last a lot).

Tbh i don't see to point of wireless keyboard and mouse.
- The battery will be always at 0 percentage when you want to use it.
- Sometimes there will be some annoying signal problems.
- And you won't able to play in serious level because of the input lag.
What is not a big deal if you are a casual player but it is a headache in multiplayer games and in challenging singleplayer games.

I don't have any recommendations for a wireless keyboard, as I don't use one, I don't move mine around, and it's in such a position that it is a problem. For the mouse, however, I use a Logitech Performance MX, a little bit pricey, but has been worth every cent so far, it has a micro-USB charging port where the cable would otherwise stick out, so it can be plugged in and used while charging if needed. I also have an M705, also from Logitech, it's a bit smaller than is common for wired mice, and perhaps not quite large enough for everyday comfortable use, but it's also not quite as small as later "portable" mice (it uses two AA batteries whereas later Logitech mice -and indeed my main mouse already mentioned- only uses one), but you'll probably start to think it generates its own power somehow as the batteries last for ages.
