Logitech Keyboard Suddenly Not Working

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

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 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. ...

For some reason, a 3rd party brand of power cable that was made for the P4K suddenly stopped working. So, even though I was only interested in the D-tap power cable for the P4K, I bought this pack anyway. Since it's made by Blackmagic, I can only assume it will always work. So, far it's working great.

Had this flashlight a very long time, and when it stopped working suddenly, the company replaced it immediately with no questions. This flash light lasted a very long time before having to be replaced. It is amazingly good quality.

My Boss Acoustimass bass module 500 just stopped working suddenly and I bought it 3 years ago. Can I get any tech support?
