Product review (5 stars): Rock Glass
Notice I said "Rock" glass. If you like sipping drinks "on the rocks", you've got to get these. The tray creates 6 giant cubes and one single cube fits perfectly in a Rocks Glass. I think the single cube actually lasts longer than several smaller ones. Also they slide right out of the silicone tray with no effort. I read a few reviews about some sort of film coming from the trays but it didn't happen to me and I bought 2 of them. Great product.
