Concerning the actual service. The LCTRL caused both of my legs to break. If you knew what kind of "song" it is to remove the clips from the keycap with a needle, you might find it interesting. I sent a message to support, and after 5 hours they got back to me with (not the exact words). You should take the keyboard to the store for repair. If the store refuses to fix it, you should produce a response from the store, and then you will need to transmit information on the breakdown directly to Logitech (they will repair it themselves). The shop will not refuse to make repairs; otherwise, everything is in order. However, if you bring a keyboard or any other product with a malfunction (issue) that is comparable to that one to the store, they will accept it and then send it to the suppliers for diagnosis and repair. This legal wrangling with the sending of the package can take up to forty-five days. And the notion of spending the next 45 days without access to a keyboard does not make me one bit thrilled in the least. I came to the realization that the next time I need to make a decision, I should probably go with a different manufacturer that has service centers in the year 2022. Extremely frustrated with Logitech's performance. The customer service and support website is typically its own distinct song (I attempted to register a product for an entire day).
