LogitechNew Unifying USB Receiver for Keyboard K230 K250 K270 K320 K340 K350 K750 K800

Very happy with this purchase. Worked for my K350 keyboard and mouse. Followed the install instructions. Lost my old dongle and needed a replacement. Cheapest replacement. Thank you. Would buy again if need to.

I had purchased a keyboard and mouse on the secondary market and soon realized that the provided USB Receiver was not working with the keyboard. Due to this, I placed both the keyboard and mouse in storage with the impression that I would "fix" the issue later. Fast forward three months and I decided to give this Unifying USB Receiver a chance and I am glad I did. And yes, I did confirm that both my keyboard and mouse where compatible with this receiver. It was quick and easy to set-up and in no time, I was using the keyboard and mouse. My only regret was not purchasing this earlier.

Does NOT work with model M/K270. I bought this for work and stupid me, I assumed it would work. I ended up spending almost thirty bucks on the same model at Target at the last minute, almost got in trouble at work being late logging in because I literally had ten minutes to find a working keyboard.. Could have bought something much nicer online, had I not been fooled into believing this was the better, cheaper, more sensible option.. Now I've got two keyboards and mice of the same model AND a worthless dongle. I guess I have replacements if anything ever breaks but... Wow. Very disappointed in the misrepresentation on compatibility. So now I gotta go return this, and I work from home so honestly that's why I had it delivered in the first place, so I wouldn't have to leave.So this is for devices that have the unifying logo on it, ONLY. So if I don't return this, I've got a ten dollar useless dongle, or I'm committed to buying Logi so this isn't a worthless piece of plastic floating around my drawers.

Works for my keyboard and mouse

As advertised and easy to set up with my cordless mouse. The old dongle stopped working and I didn't want to buy a new mouse. This was a inexpensive fix and the set up instructions were easy and fast!

This is a good dongle unit for my mouse and keypad. Leaving it in my laptop and transporting my laptop daily from JOB to JOB, the dongle lasted about six months before I had to replace it because of internals either breaking or shorting out, but it was a very good unit while I had it.

It's such a little thing...literally, but so important! I lost my USB receiver several months ago and have been unable to use my favorite keyboard. AND it was very difficult to find another one. I had previously purchased one from another seller but could not get it to sync with my keyboard This one came with super simple instructions, I followed them, and was connected instantly! Yeah! I'm so happy!

To be fair, the keyboard I bought didn't have a usb and I was trying to find a universal one. Perhaps for this brand there is not one?? I just know when I pulled it it, it did not connect to the keyboard.
