Caffeine Molecule - Glass Coffee Mug - Makes a Great Gift Under $15 for Science Buffs!

This is a great mug. It's durable and strong and it feels good in your hands. It's a lovely mug.The chemical symbol is not too bold and it definitely gets the point across.The simple design is good, but it would probably make more sense to draw the symbol in another way-- but maybe they ran out of space. Either way it's GREAT! I bought 3 :)

This is of great quality and its a bit heavy which is good, its not easily breakable, although it is glass. Very nice work and great clear color.

This is a nice mug with what appears to be very high quality printing. FYI, contrary to what the Amazon site says, the bottom is not perfectly flat, it has a small ridge on the bottom. (This only matters if you are putting it on a warming plate, which are more effective if the bottom is perfectly flat). But an hour or so of hard work sanding, and I now have a flat-bottom coffee mug. Very happy with this product.

cool that it has the chemical compound. weird that there’s a line down the middle like they made 2 pieces and melted them together or it’s from excess where the mold fit together and this cheap?it’s glass so no lead like crystal, ceramic, etc.it’s glass so no phalates leeching like plastic to ruin the last and your health. it’s fairly sturdy and not insanely hot, i bought this to try after the cats broke all of the borion (i think is the brand) insulated glass cups, where they have a air gap in the walls to keep the heat or cold from burning/sweating.

Good quality, made a good gift

Chemical skeleton hasn't faded after 6 months.The bottom inside is flat and there are no crevices, so it's easy to clean. I've been using it for espresso drinks, tea, and french press.Heat dissipates pretty quickly, but you knew that -- it's glass.It's quite heavy -- the glass is pretty thick. I oddly found I really like the feeling of a heavy mug.

This mug is awesome, but after one go in the dishwasher a piece of the rim chipped off. We still use it as a flower pot bc it is really cool. Just wish we could have been able to use it as a mug more.

I won't buy this again but it's awesome. My girlfriend loves it. The print is good, it's on both sides. It's clear, im an idiot and didn't know that because the stupid picture shows it as filled and there's two pictures on the display with the same filling so I thought it would be that way and it made me sad buuut no, it's clear glass and it holds a good amount of coffee too. My problem is that the handle, while never getting hot, is too small. Way too small for my fingers to wrap around. And the inside of the handle, has a protruding line where it was connected to the other half and it's annoying and hurts. It's so annoying honestly. But it's not mine so -2 stars. It's a mug, there's not much to review. It's safe to wash it anyway you can wash, I guess and it really does look cool to have in the cuppards.
