This solder mat comes in handy when working on small parts as all the little indentations help keep things organized and neatly separated from everything else. The silicone mat lays flat and flat with no lumps, bulges or twists. The Weller solder pad I received doesn't look like the picture. The layout is basically a mirror image of the advertised photo, only the placement of the Weller logo has stayed the same. The three compartments with lids are on the top right and the magnetic compartments are on the left. A ruler is molded into the top of the main work area, but it's very faint and almost impossible to see. Ditto for numbering and labeling small detail cutouts, making them practically useless unless you have perfect eyesight. They could be really useful if they were painted a bright contrasting color like they proudly did for the Weller logo on the mat, but for now they're of no value or use to me. withstands up to 570 degrees Fahrenheit, and since most soldering work is done (or at least should be done) with a tip temperature in excess of 600 degrees, you don't want to touch the soldering iron tip to the mat lest you cause unwanted damage to it. However, it does hold up well to things like flux splatter or the occasional drip of solder. Three small closed compartments are a nice touch. They are very flat when the lid is closed and require a bit of fiddling to press them in properly all around. For me, it ends up being another good idea that's poorly executed. I'll probably just grab a razor blade and cut off the flaps to get them out of the way for good. The overall thickness of the mat is acceptable, if a bit disappointing. If someone accidentally puts the tip of an iron on the mat, not much material needs to be burned through before it reaches the underlying surface. Depending on how you look at it, it can be both good and bad.
