You know someone who has those! You been there done that.
The only issue I have with them is #1 they are heavy. I don't need people spilling more liquids around here due to the weight of them. #2 they are not as large as I would like them to be for the iced tea, (ie hold enough) as you have to refill it too often.
The ice in the tea will melt in 5 seconds, so I have the tea chilled, and then an ice bucket with the ice. People can use the ice for their other drinks too if they want to. One man is walking around with a bottle of Dr Pepper and he is using the ice.
Back to the orig topic, I really do LIKE those tho, they don't dilute the fluid like reg ice melting into it. That was why, like you know for say a bridal or baby shower in the old days, we would freeze 7 up or lemonade to put into the punch bowl so it was not diluted, but more of the same ingredient..
