A:AnswerHello George! The USB receiver from the MK295 Wireless Membrane Keyboard and Mouse Bundle isn't sold by itself unfortunately, but you do have a 2-year warranty on the Bundle with Logitech, so I would suggest possibly reaching out to the Logitech Customer Support so see if this is something they might have as spare parts by going to the product page and clicking Support: https://www.logitech.com/en-us/products/combos/mk295-keyboard-mouse-combo.920-009782.html
A:AnswerYou don't have to hit the keys that firmly to type, but you do have to depress them all the way down. To me, there's a very satisfying "clicky-ness" to the keys, and I find the action crisp and responsive. If you like typing on keyboards like the Apple Magic Keyboard, this will feel a little stiffer. Not as stiff as those old-school keyboards from the earlier days of computers, but definitely more firm than the nearly-flat keyboards of Mac-world.
A:AnswerHello, unfortunately, you can't remove the keycaps. It will break the keyboard. If you're looking for removable key caps, we recommend looking at our K845 mechanical keyboard. Thanks.
A:AnswerHello Damian! All of our Mice & Keyboards solutions have an encrypted wireless connection, yes, including the MK295 Full-size Wireless Membrane Keyboard and Mouse Bundle. Logitech's Advanced 2.4 GHz provides 128-bit AES encryption between keyboard and receiver. Now with our newer products launching and including the latest Logi Bolt Receiver, you're getting even more protection. Logi Bolt is engineered with Bluetooth security mode 1, level 4 (also known as Secure Connection Only mode), which is Federal Information Processing Standards (FIPS)* compliant. That means Logi Bolt enforces security by means of encryption. Level 4 uses Authenticated LE Secure Connections (LESC) encrypted pairing—specifically, Elliptic Curve Diffie-Hellman P-256 (ECDH) and AES-128-CCM encryption. - Mathieu from Logitech
A:AnswerHello Bonnie! As long as your OS is Windows® 10,8,7 or later, you'll be good to go yes! All you have to do is connect the Nano USB receiver into one of your All-in-One computer.
A:AnswerYour answer makes no mention of a USB hub. Although it seems like you are saying not only will I need to use a USB plug for this keyboard but if I want to keep using my current USB mouse I have to use separate USB plugs for each. Not optimal.
