Logitech MK240 Nano 79-Key Wireless Keyboard w/Mouse

I opened everything in order to install it and where the dongle was supposed to be in the mouse and where it clearly states it was not in the mouse itself. spent a bunch of time looking for it and decided to return it but then when I was packing up the box, The dongle was attached to one of the cardboard edges. Very easy to miss!

I bought this set to replace the exact same (or so I thought based on model numbers) set I had because my old keyboard started to have issues. As someone noted previously, the USB dongle is not where they said it should be (i.e. in the mouse's battery compartment) but was tucked into a slot on the box the set came in -- easily missed until I was going to return the set. So, fine and well -- I got it all connected, cheap mouse and all. But I'm no happier.I'm extremely disappointed to see that this set is no longer compatible with the Unifying Receiver, meaning I can't use my favourite (non-cheapo) Logitech mouse without using up a second USB port for the Unifying Receiver for it. The whole point of the Unifying Receiver was so you didn't have to have several USB ports being used up for your external peripherals. (I might as well have a wired keyboard and mouse if I'm going to have to use up two USB ports anyway.) I don't know what Logitech was thinking -- wish I'd read more of the reviews before buying this set.Giving it two stars only because the keyboard seems to be functional and familiar; otherwise this would be a one-star review

I've never had a keyboard as bad as this one. The keys don't respond unless you really press hard and God forgive if you want to put a space between words. Have already ordered a replacement and I have only been using this one for a day. I really got the lemon of the bunch. The only reason I ordered this was because of the reviews. Cannot wait for the new one to arrive. Sorry, can't recommend.

*Update* This keyboard has made it's way to the electronic recycling program. Absolutely the biggest piece of garbage I have ever purchased. The mouse works fine but the keyboard doesn't respond at all. Second one that I had (first one had the same issues and was replaced). Save your money and get something else.I had the first set I bought replaced because the keyboard would become non-responsive or delayed right from our of the box. Now the replacement keyboard is doing it again after about 6 weeks of use.

I was looking for a full size wireless keyboard that would not take up too much space on my desk. That meant looking for a full size keyboard with a numeric keypad, but without large border of wrist pad.I use this keyboard 10+ hours a day, as a professional software developer. I wanted clicks with a positive feel but without being as noisy as mechanical gaming keyboards, and without the keys being as tall as on gaming keyboards.So far, after using it for a couple of days, I must say that I am impressed, considering the low cost of this keyboard.I don't use the mouse that came with it, as it is too small for my hand. In a pinch, I could use it for short periods of time, but I'm sure I would be uncomfortable bordering on wrist pain if I used it for any length of time.The media keys on top are actually quite useful. I especially like the calculator one, as I often need to pop up the Windows calculator for a quick calculation as part of my work.
