Logitech Keyboard Sound Buttons Not Working

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

Gives all the buttons I need. And I don't look like a weirdo with a full bluetooth keyboard when working in a coffee shop.

Love this keyboard, good design by Logitech and very comfortable.

I've been using this keyboard since they came out from logitech. These are the only keyboard mouse combo i use.

I use this to switch the monitor, mouse, keyboard and sound between 2 computers. It's been working flawlessly.

I really enjoy the convenience of having a wireless keyboard and the K750 Solar Wireless Keyboard from Logitech is the best one in my opinion. It never fails me and is quiet and charges while not being used from normal light in my home.

I have been getting Logitech electronics for years. When I first purchased the MK710 Wireless Unifying Keyboard and mouse at least 10 years ago it immediately became my go to keyboard/mouse. Since my first purchase, I have gone through 3 of this item - due to my cats using my keyboard as a bed. I have looked at other paired keyboards and mouse, but always select the MK710 due to its comfort, ease of use, and because I love it. Until, and if, Logitech creates a better unifying Keyboard and mouse, and so far they have not, I will keep purchasing this item when needed.

I enjoy very much that Logitech MK270 Wireless Keyboard & Mouse. Although its a very comfortable product and my best keyboard choice, its still very cheap to get it!!

I got the best price and a rebate at B&H. The Logitech illuminated keyboard is totally slick. ...

This is my second Logitech ipad folio. It is well designed and I like the flap that has been added to secure it. (And hold a stylus, if used.). My only minor complaint is that the corner piece that covers the + and- buttons that control screen shots and volume is so thick that I have to slip the corner cover off to use those buttons. Other than that small issue, it is a very nice product.
