Cool glass
This is a cool mug especially for cocktails and iced coffee. I usually use it for cocktails since we don’t do iced espresso at home just regular lattes. Regardless, this is a nice quality thick glass with clear markings on the side of it to tell you roughly what’s in it. Kind of fun novelty and the caffeine molecule on the front is a nice touch.

Cool as heck. Love it
If you’re not familiar with Amazon Vine, it’s a program where reviewers get products in return for honest opinions. Some reviews can sound a bit generic, but I try to keep mine practical and genuinely useful.Even though the items are free, Vine members do pay taxes on their value, so I only request things I truly intend to use. I mention this because it matters, there’s no incentive for me to oversell a product. If something is great, I’ll say so. If it’s not, I’ll be just as open about that.I love this glass coffee cup (beaker?). As I try to move away from plastics and plastic coatings, glass has become my “go to”. Coffee is something I drink every day and when I saw this unique cup I had to have it. It looks great and is the perfect sizeA few considerations - most people like hot coffee. Thats why they have always made thicker ceramic cups. They hold their heat longer. Especially when pre-heated. This glass cup is rather thin and it will not hold heat for a long time. While this is not a problem for me because I preheat all of my cups, it may be something you should consider if you drink your coffee very slow.All in all I am completely satisfied with this item. If a person works in a laboratory or science dept setting and drinks coffee, I can’t imagine a better gift for them. I don’t work in a laboratory and I still love this cup. At the current price of around $15 I think it’s a fair value. Mostly because it’s unique and you can’t find stuff like this anywhere else. If the price went any higher than this, I would have to reconsider.

Would make a thoughful gift for science teachers, co-workers or anyone who likes chemistry.
The mug is very uniformly shaped, the top is level all the way across. The "caffeine" molecule is also very well placed on the mug. The bottom is also flat and uniform. The handle is large enough most hands should fit easily through it. When filled with coffee there was plenty for a decent amount of time. Those who drink coffee all day or at least more than one cup will have to refill it just like with all their others.It does not keep the coffee really hot for that long of time, but that is not the idea of this cup. It was definitely a conversation piece amoung my co-workers, which is the actual purpose of it. I would say the thickness of the glass is nothing but ordinary. But it is not so thin that you would worry about cracking or breaking. You can microwave it no issue. As far has going from really cold to really hot, I am not sure it is not made to withstand that type of thermal shock. I like the mug so I did not test it for this :).One other things I wish would have been different about it is that it is much taller than it is wide. This makes it a bit unsteady and will be unforgiving if you place it down on an uneven surface. Like stack of papers, only have of your coaster, on edge of placemat or anything etc. I tend to want my coffee mugs to have a wider base.

Good quality mug with clever sciencey logo
Considering caffeine is the main reason I drink coffee - this mug is just perfect! I've also always enjoyed the look of a clear glass mug for coffee and tea, but don't see very many in the classic straight sided mug shape. Very happy with this overall, it's easy to clean in the dishwasher and seems thick enough that it will hold up well over time.

Morning caffeine!
This glass mug is perfect for any scientist in one’s life! The mug has the molecular structure of caffeine on the front, making it a perfect mug for one’s morning coffee. For the chemists, the glassware will fit right in with all of the other glassware in the lab.The glass is on the thinner side, making the mug light and easy to carry. The handle is large enough to comfortably insert one’s fingers. Despite being thinner, the glass spfeels sturdy & substantial.

Good looking mug, easy to hold, and well made.
Overall I like this coffee cup. It's decently thick glass and I won't be overly worried about breaking it accidentally, although I'm sure it would be problematic to drop.The designs on the glass are well printed and decently easy to see, of course this is easier against a dark background or if you have a dark liquid in the glass. The measurements on one side complement the designs on the other.The handle is large and easy to grab which is great, and the edges of the mug are rounded which makes for a pleasant drinking experience.In all, I think the vast majority of people would be very pleased with it whether for themselves or as a gift.

One of my Favorite Mugs.
This is one of my favorite mugs now.It feels like my laboratory equipment. Thick and sturdy, even and balanced. I trust implicitly that it's going to withstand heat and cold fluctuations. I heated a cup directly on the stove with this cup and it was fine. It was fine in the microwave. I haven't put it in the dishwasher yet but instructions say to hand wash, and that's all I've done so far. Holding the handle while I was drinking my tea felt so nice and roomy.It has quickly turned into my favorite mug.
