These glasses help elevate my wife's new super automatic KF8. Being able to see through the glasses make the cappuccino/macchiato pulls that more appealing. Also, large whiskey cubes fit in the mugs nicely when I brew over ice. The variety of the two different types of glasses in one set is hard to find elsewhere and I'm super happy it came from a brand as great as zwilling.
The craftsmanship on this set is amazing, crystal clear and no blemishes. They're light, yet sturdy. They retain heat very well and they wash easily and barely get any water stains (compared to other brands). Having two different sizes works great for both hot and cold drinks. The spoon/straws are a very nice touch, as well as the included cleaning brush. Overall, we are very happy with them.
