Sorry guys I couldn't do a video review because the room is in a real mess.
It took me about 10 months to use up a yellow CyberClean (eventually it dries up and gets shiny and stops picking up anything else - leaves a greasy mark), so I was pleased when the blue arrived.
CyberClean just works. Plop it on a keyboard and let it sink in (squish it at first, but you will get better results if you can leave it for a few hours to sink into all the corners - it does dry up a little quicker this way) and you'll be amazed how much fluff comes out. Use it on the mousepad on a laptop, clean the screen of mucky bits (though still use a proper screen cleaner), clean up the bottom of a slidey mouse, clean up a smartphone, all sorts.
The blue is supposed to be for use in a car or caravan. The main difference is that the blue says it can stand extremes of temperature ie being left out overnight. It does the job for me.
You can also take imprints of coins and medallions, though it isn't very good for making plasticine-type figurines, they flop down over time
