I just received today 2 sets (4 pieces) of this 9 oz. driinkware. I have several double walled smaller glasses for espresso, wine, and other beverages. I really like the insulation, the clarity, and the broad, flat base to resist spilling. These have more space between the walls than others, promising better thermal insulation.
I'm giving these 5 stars and may also try the 'tea' version. I have a suggestion, not a complaint, but I wish the diameter was smaller. They're are a little wide for smaller hands.
This was an excellent product. I don’t see condensation at all and it also keeps my hot drinks really warm. Can’t say enough good things. Best purchases I’ve made in a while.
