Product review (5 stars): They were easy to use and easy to get the cubes out ...
I received them and washed them in soapy water and used them right away. I noticed they froze quicker than my hard plastic trays which was a plus. They were easy to use and easy to get the cubes out too. Our drinks stayed colder longer with just the one large cube rather than 3 small ones so that was a plus also.  I give them a 5 star review and will defiantly buy another one.
