Bought these for our house. My dad came over and used one and liked it so much, I now know what I will be getting him for his birthday!
The only complaint I have is that the silicone ring should be higher up on the glass so it’s easier to hold on to.
I bought three sets, whiskey, wine and margarita. I love them.
Got these for my Dad for Father's Day. He loves them- says he can enjoy his scotch cold and undiluted.
I use them in place of ice and they work like a charm. They make warm drinks fridge temperature, and already cold drinks will get colder and sometime slush. Which is my favorite part... a slushy coke is always nice.
