Lost Usb Dongle For Logitech Keyboard

The touch of this keyboard is so nice that I bought it for a second computer that was using a Logitech MK545, which is a great keyboard, but pales in comparison to this one. After using the MX Keys for a while, I found myself disappointed every time I had to use the MK545 for an extended amount of time as the two keyboards are worlds apart in terms of finger touch when writing for an extended amount of time. It is also backlit for such a compact form. I just wished the battery lasted longer charges, usually about a week with my usage. It also seems to use the standard dongle found among all wireless Logitech products, just not compatible with the dongle of the MX Master 3S mouse.

No skips with keystrokes to USB dongle. Every stroke comes through. The keyboard itself is basic but has the features needed for my job; numbered keypad to the right and a few quick buttons. Overall, I give this product a 5/5 rating for the price and function.

I was using a wireless keyboard at the limits of its range. So I got this USB extension cable to get the wireless keyboard USB dongle closer to where I was using the keyboard (about half the distance). So far it's been working great. However, I haven't tried any USB device that requires power, so I don't know how well it would work with those devices.

I got this to use with my laptop, great wireless keyboard with comfortable mouse !!! Usb dongle just plugs into laptop and no hassle with wires worth the upgrade.

When combined with the widi bud usb dongle you have a truly wireless Bluetooth midi keyboard that is slim and works with negligible latency which is great for portable musicians and producers.

I love that the USB dongle has a slot in the keyboard in case you don't need it. It's definitely worth it to replace you wired keyboard with this one, especially if you already use a Logitech unified mouse.

I use this keyboard on my desktop computer and I have to write that it undoubtedly has to be the best performing keyboard around. The great thing about it is that it requires no batteries, its corded (USB), so there is no lag time between the computer and the keyboard as battery performance winds down. The keys are quiet while typing and easy on the touch (short key stroke). Of course being from Logitech, the software is an easy download from Logitech and the keyboard is fully programable. Another great thing is that it is low profile and sturdy, it has some weight to it but not bulk, so it stays put on the desk while typing and of course, it is illuminated and has variable illumination at the touch of a button. Multimedia? Of course, more than I would ever require but it is there for the web surfer if needed. Probably the best feature of all in my opinion is that it is a USB keyboard, meaning no batteries to buy and personally I have never been fond of wireless from the beginning but somethings leave you no choice but then again, Logitech does. If there is anything about this keyboard that I don't like, I have not found it as of yet and I have two of them, one I have been using well over a year now and another thing is that there are no character decals on the keys, so no E's or T's falling or rubbing off after a months use or so. So, if you are not into wireless, purchase this keyboard from B & H, you'll love it.

I got this for my Logitech MX mini keyboard, does what it is made for.

Connected right away with dongle. Installed Logitech Options and used that to help connect second system with a second dongle. Both working well with a simple key switch.

I was disappointed to learn that logitech had discontinued the M570 trackball, but the M575 is even better. It has built-in bluetooth or dongle (usb) connectivity.
