    Cannot be cleaned!  NOT RECOMMENDED

   The double layer of glass is meant to insulate but there is a tiny drain hole and if water gets inside - which always seems to - it is impossible to get it clean between the layers.  The result is that the cup always looks cloudy and dirty.

### ⭐⭐⭐⭐ 







  
  
    Not really the size they state.
  

*by R***E on Reviewed in the United States on March 18, 2019*

My mistake was thinking that the 2 cups were not different sizes. That being said, they state that the small cup holds 4 1/2 ounces.  If you put that much in there it will be floating at the top of the rim.  Now for the 14 ounce cup. NOT even possible. I put 12 ounces in and it was to the very top of the rim. I would consider this a 10 ounce usable space. I haven't tried them yet so I will let you know once I have if they are worth the money.  They are not very thick so I worry they might be easy to break.

### ⭐⭐⭐⭐ 







  
  
    Great for espresso drink lovers!
  

*by R***N on Reviewed in the United States on January 11, 2019*

I really like these glasses. Perfect for cappuccinos and espresso. They keep the drink warm longer than a regular ceramic coffee mug and the clear glass let you enjoy the look of a hot cappuccino with a nice froth. Outside of the cup does not get hot so you can hold onto it without burning your hand. Very easy to clean. Sad to say I broke one very soon after my purchase by being careless while washing. Dropped it in the sink when it slipped out of my hand. Overall, I am very satisfied with this purchase and will likely replace my broken one soon.
