Review on Logitech MK345 Wireless Combo Right Handed Computer Accessories & Peripherals for Keyboards, Mice & Accessories by Susan Klauder

FYI This keyboard is NOT compatible with Unifying receivers (for example, you can't pair it with other Logitech Unifying products like the MX Master mouse). An error is thrown when attempting to pair the merging receiver. The only way around this is to use TWO USB receivers, which is totally impractical on a laptop with limited USB ports. Another way to tell if this is the case is to compare recipients. The combo receiver is black and generic without a single logo on it (left), while the merging receiver (right) includes an orange merging logo. It's disappointing that Logitech doesn't make this clear up front. Now I have to take the time to repack it and send it back. If Logitech had made it clear in the description I would have just found the right compatible pair.
