I'm interested in electronics. Nothing serious, but I solder and repair various audio equipment. It was a pleasure to have this rug. The magnetic areas are good for holding an extra screw or whatever. Space for my tin container and space to organize toothpicks and shakers. The fact that it's fairly solder resistant means there are no more flash points on my desktop. For the price, this turns out to be one of those things you've probably always needed but didn't know you had.
