I have received several compliments on my mug. As a chemist, I was surprised to find so many chemistry and physics related equations... so it is not just for the mathematicians! It is great for physicists and chemists as well.That said, it is funny shaped mug. Short and wide. It holds 11 ounces I believe (and general mugs hold 12 ounces?? - so maybe slightly less volume). The handle is a bit odd as well. It is not very wide, so I put only two of my (female) fingers through it, when usually I would use three fingers on a mug handle, so it could be uncomfortable for some people to hold.I have had it for several months now and not a single chip, so no complaints against the material, though I haven't tried banging it against the sink yet.Plus for those people who never clean their coffee mugs, the great thing about having a black mug is that it doesn't show what you were drinking the day before. And there are definitely several professors out there with disgusting white-turned-brown mugs.UPDATE 08/14: About two years after purchasing this mug, I dropped it on the floor and it broke. So I promptly bought a new one (no brown-stained white mug for me) and it is slightly different. The old one had a clear glaze over the whole mug, so it was shiny black. The one I just received does not, it is more of a matte-gray/black, which I imagine may be to make it look more like a chalk board. Notably, the equations are now the top layer on the mug. I hand-wash only my mug since I just leave it at work, but I was concerned upon seeing this that if you use a dishwasher the equations may wear off (but I can't say for sure since I never put it in a dishwasher). It still has that funky handle I mentioned initially.
