The tumblers have a great weight and feel. They look classy and keep ice from melting longer than an ordinary glass. Not as well as the double walled stainless but you don't get the metal taste like you do with those. Plus it looks a lot better. The capacity is perfect for an Old Fashioned with an ice ball. I would be careful putting the ice ball in, however.
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.
