    DO NOT BUY, NEAR FRAUDULENT, in my experience and opinion! i will never buy logitech because of this product(and one other), best buy has lost a great deal of respect for carrying this product and selling it to me, why am i not buying from amazon instead if the product quality control is no different? i have purchased two of this exact thing a year an a half apart, and they both have the exact same issues. both the mouse and keyboard CONSTANTLY disconnect and reconnect while you are in the middle of typing or moving the mouse. the amount of lag delay is unheard of in the modern day. the stuff in the 90's was higher quality. when it disconnects, it will stop typing, but it will remember everything, so while your trying to figure out what is going on, when it finally reconnects it will spam everything you typed while it disconnected. i have tried updating the firmware, the drivers. there are none, they make you download their bloatware(useless), and there are no specific options for drivers or firmware(their firmware update software will not recognize product). and even so, i got the same exact model over a year apart, if it was a driver issue it should have been updated in the product by now. if a billion dollar company cant provide a full product at sale, how are they still a billion dollars? i would define this as literal fraud on logitechs part, and best buy should be ashamed and holds partial responsibility i think. i have hooked this up to 5 different computers, with or without the dongle, it behaves this way. my current main computer is brand new, and modern. it is not anything but this product at fault. i have been a lifelong exclusive to logitech mice and keyboards my whole life. i will never touch this trash to me company again, something seems to have happened to their quality control, perhaps they write it down for tax purposes but dont actually invest in it?

    high pitched noise from the mouse scrolling wheel

    Keyboard is bluetooth, which is excellent. keys are very smooth, silent and big enough for my fingers to type correctly. mouse is also ok, supports 3 devices, but what I don't like is the high pitched noise it produces randomly when using the scrolling wheel. this high pitched sound is annoying after a while. I returned the original one, and replaced for another k/m combo. I hope this new one doesn't have the same problem.

    Bluetooth pairing inconsistent after a month

    I really love this keyboard. It's wireless, and can switch between three devices. I have it paired to my work laptop and personal laptop. I like the slanted area to rest your wrists. Overall it's very comfortable. I've had it for a little over a month and it's been working amazing until the last couple of days. Today alone, I've had to unpair and re-pair the keyboard with my laptop four times. For some reason the connectivity with my Windows 10 laptop is starting to act up. I was in the middle of writing email and it disconnected from my computer. Nothing in regards to my computer has changed; the laptop is the same, I haven't had any updates done to the system. The keyboard is disconnecting at random times. I'm very frustrated as I'm now past my 30 day return period back to Best Buy, and I'm constantly being forced to go into my settings and re-pair the device to my laptop. What's the point of getting a wireless keyboard if it can't stay connected. A waste of money, please look elsewhere.

    Touch and Feel a Little Clumsy

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I work from home as a systems admin and was desperately in need of a replacement keyboard for my Microsoft. I type 105 wpm, so the touch and feel of a keyboard is critical. Coming from a Microsoft keyboard, I find the touch and feel of this Logitech to be quite clunky and noisy. The keys also appear to be slightly smaller or angular, resulting in quite a few typos. It's not a bad keyboard for a non-performance typer, and I do like the palm rest, so I'll keep it and use it for one of my Smart TVs, but will need to replace it as my primary keyboard because it's quite clumsy for me. Also, Logitech has very poor instructions on their site. To download the manual you need to first register the product, so don't destroy the box it came in. The S/N is on the box - not the keyboard. When you register, you have the option to download upgrades, the manual for mouse/keyboard options, but the manual to how this keyboard works (features) you just won't find. You also won't find instructions on how to connect to Bluetooth, so be sure to keep the box. It's unclear why it's so hard for manufacturers to include reasonable instructions for keyboards/mice. All the questions being asked on this page, you will not find in the manual.

    I am not happy with this keyboard. First of all, I didn't realize that the keys were not backlit. I like that it can be paired with 3 devices, but I can only seem to pair one device at a time. The keyboard ofen goes out. It's paired as a #2 device, but the mouse is paired as a 3 in order for both of them to work with my pc. I tried to exchange it at the store for another keyboard but was told that it could only be exchanged or returned within 15 days of purchase. I wish that they had pointed that out when we bought the keyboarf. We were already in the 25th day when I decided to contact Best Buy. I was trying to see if i could live with it, so was giving it time. Now im stuck with this.
