I have a Logitech MX keyboard and it has a pretty bad design flaw that Logitech refuses to acknowledge even though hundreds of people have complained on their forums.
The backlight on the keyboard CANNOT be permanently turned on.
It uses a proximity sensor which only works 10% of the time or your hand is so close that you're better off just pressing a key to turn it on.
Unless you are constantly typing then it defeats the point. You take your hands off the keyboard, 10s later backlight goes off. Now you can't see anything. Then you have to wave your hand around above the keyboard because the proximity sensor is limited to a small area of the keyboard. At this point it's easier to just press space or something to turn it back on.
Really really bad implementation on a pretty expensive keyboard. Shame they carried the flaw over to the newer MX models.
The coolest thing I ever did: I wanted a WIRELESS KB n mouse to reach from my bed to the PC I used as a bedroom TV at the end of the room. I had 3x 1.5m USB 2.0 extension cables lying around. Connected them to form 4.5m long cable. Ran the cable underneath the bed sheet below the pillow so I can shift around in bed and it does not interfere, plugged in USB hub at bed end. TOTAL COST USD $7 shipped for 3 USB 1.5m cables plus cheap USB hub. I now have a WIRELESS KB n mouse combo only I used a wired KB and mouse set instead and the response is instantaneous even good for gaming. NOT only that I never have to worry about the battery powering the so-called wireless se!!
