I had high hopes for the K270 wireless keyboard. But it has been replaced by an old-school traditional USB keyboard. Logitech K270 started to work. I could sit with it on my lap and with a Logitech wireless trackball (fantastic) on the armrest. But about two months after the end of the warranty and after-sales service period, it started to fall behind. That said, I could press a key and it literally took (and I use "literal" for a reason) 5-10 seconds for the letter to appear. If I got impatient, I could press the same key multiple times and then 15-20 letters would magically appear. It happened in word processing, email, whatever application I was using. Various comments online suggested that this was not uncommon and suggested possible treatments: change the position of the combiner chip; Connect directly to the computer, move things around the table. Nothing worked and nothing worked. While I lean in, the overall build is cheap. Key movement is free and clicky. But I could live with that. I can't live with the 10 second email delay. If you try any of these, keep an eye on the warranty period and return to this window if necessary. Much luck!
