This mug truly has the look and feel of laboratory glassware. I really like it, in that respect.
Note that it's not a very good insulator, which has implications on both the temperature stability of the mug's contents and the potential for heat transfer to/from skin that may come into contact with the outside. Since I use it only for hot liquids and prefer to drink them at more lukewarm temperatures, I consider its heat conductivity a feature.
My only real complaint is that it's just a bit too small. The capacity is barely sufficient for me to fill it from the single-serve coffee maker in my office and carry it back to my desk without spills. And while the pour spout is a nice feature, I end up using it far more often as a "spill spout". :-[
Finally, there's the handle. As with the body of the mug, it's on the small side. It's a squeeze for me to fit 3 fairly large fingers in there, and then they're too close to the glass if the mug contains very hot liquid. I've found a way to hold it with two fingers my index finger hooked through the handle with my middle finger also curled but on the outside of the handle. This gives me stability and control, while minimizing the chance of accidentally touching the mug's body. I find this makes it relatively easy to avoid spills on the way back to my desk, so long as I keep an eye on it.
Prior to this, I had a much larger beaker mug of a different brand. It had the opposite problem of being too large. Its markings went to 350 mL, but probably held about 450 mL when filled to the brim. Its size presented a few logistical problems (coffee maker incompatibility among them). Even so, I continued to use it until I inadvertently discovered that, strong as it may be, borosilicate is no match for concrete (for v ~= 2.5 m/s). Rather than replace it with same, I opted to find a more practical size. I think I can now conclude that my ideal size would be about half way in between the two.

Great gift for my daughter who is majoring in Biology...she loved it! It is lab quality, not a novelty like some of the others on Amazon. Very happy with my purchase.Best Deals for Premium Beaker Mug, Thick Borosilicate Glass, 8.4oz (250mL) Capacity

What a clever idea!! They shipped super quickly and were exactly as pictured. They were packed securely so no need to worry about breakage during shipping. Can't wait to have some guests over and break these out. I might have to order some more!
