Nice design but leaks where the lid and the cup meet. Not very impressed. Two stars instead of one because I’ll still use it around the house without the lid.

I wanted a glass cup so I could watch in amazement as my espresso slowly infiltrated my steamed milk, and this does the trick. Just barely fits under my Flair 58 and is a great cup.

Love this little cup. My one comment is that unfortunately it does not keep coffee warm for long. Otherwise it is preferable over other travel mugs and cups because if esthetics and sustainability.
Care must be taken as it is sturdy but still delicate.

I really love this Mug because I prefer drinking my coffee out of glass whenever I can. Just prefer the aesthetic and the clarity that comes with it, plus I find with some ceramic/metal travel mugs they tend to be hard to clean and end up affecting the taste of the coffee. So if you also prefer glass, I think you'll really enjoy this mug! Feels exactly like drinking from my glasses at home, so it's my go-to travel mug now, but it does have a couple cons so I'll try and list them off:

- Firstly, this mug is a bit small depending on how much you brew. I brew 350ml in the morning, and for some reason thought this would have some wiggle room but no, its basically at the exact top where I can barely get the lid on anymore. I had to buy the larger version, so while its not the cups fault, just an FYI it may be too small depending how much you are brewing.
- The glass gets really hot, and the silicon/plastic piece also gets uncomfortably hot in my opinion. I don't mind grabbing it shortly after I brew and bringing it to my car cupholder, but I don't think I could stand holding it constantly if I was walking to a bus stop or something and didn't have a place to put it down. Perhaps the cork model is a better insulator, but I brew at near boiling and if you are trying to brew then run, it may still be too hot
- The lid feels pretty secure, but definitely not as secure as other travel mugs. I feel comfortable walking with it but if you try and lift it by the lid or hold it the wrong way it can pop off very easily.

So overall, if you are careful while traveling with this and love drinking out of glass I'd definitely recommend this mug! If you brew more than 300ml in the morning I'd suggest going for the larger version, but I've made the 350ml work just need to be careful.

Enjoy!

From a quality and functionality standpoint it's great! I had concerns when reading reviews that the cup would leak but none of those concerns were substantiated. This works no different from a paper cup. The materials feel high quality.

Aesthetically it's okay. I'm not a fan of the lid design. The roundness, two tone bright colors make me feel like I'm drinking from a toddler cup. Oh well... I'll take a hit on my pride to reduce my paper cup dependence.
