Product review (5 stars): awesome cubes
I know they're just ice cubes, but I love that they last for a few hours, and you only need one per glass.
I also make them with ice tea, and juices, so our drinks don't get watered down. They need to be scrubbed when you use anything other than water, but they don't remain discolored, just takes a little more work to clean them.
My friends love them too... I recommend these!
