Got this to replace a previous Logitech Bluetooth keyboard & mouse combo, which I accidentally destroyed the USB dongle on & it seems that you can't get replacements parts for!
Well let's look at what you get.
The keyboard itself, a very small USB dongle which is not much larger than your (adults) thumb nail, 2x Duracell batteries & a USB extension wire.
Setting up is a bit hit & miss, as there's no instructions to speak of, just diagrams!
Just plug the dongle into USB extension &/or dongle into a spare USB port & let the computer get on with it for a few moments, my Windows Vista x64 found the right driver for it quite quickly.
Whilst the computer is looking for drivers, pull the yellow tab out from the back of the keyboard (there are two AA Duracell batteries already in it) which activates the keyboard & insert the two AA batteries that Logitech supplied into the mouse & switch it on if it's not already switched on.
Pop the software CD into the computer, load up the software + maybe a reboot just to complete the setup.
BTW There's a new software driver already available if you want to download it from the Logitech website (for me a 26.6Mb download).
The keyboard is very light & the key presses virtually silent, maybe a very slight noise but definitely not clicky like a cheap keyboard, the keys are slightly curved, there's one reservation I do have with it & that the markings appear to be stick on letters, so how well these will last compared to the laser etched ones I don't know.
There's a small LCD display at the top which shows you battery level, whether the caps lock is on, scroll & number lock is activated or function key is pressed. There's a calculator key on there too, which brings up the Windows calculator & just above that is a small recessed on/off switch.
The mouse is nice & compact (it's designed for right handed people) on the bottom is a on/off switch & small battery compartment for you batteries as previously mentioned.
Left hand side of the mouse two forward & back keys, on top the normal scroll wheel & a small button. Well I say normal, it's not quite normal, flick it and it will whiz round at a great rate of knots, which is ideal if you have multi-page documents or long web pages, however this is where the small button comes into play, pressing the button stops the high speed scrolling & brings it down to a much more controlled scroll which is very slightly notchy, but makes it a lot easier to control things.
Logitech reckon you can get 3 years battery life out of the set of batteries supplied, I wait & see what happens with it.
All in all a nice comfy keyboard & for £50 a good buy, especially as it's on sale on the High Street & other online retailers for near double that!
