Product review (4 stars): decent for the price
I got these primarily for scotch and whiskey as they melt less than two or three cubes.  These do the job but I have 2 comments.  The tray rubber is a bit flimsy in between the cubes so the cubes aren't perfect cubes.  And because the tray is so flexible they easily spill when I'm loading it into the freezer.  So now I fill them 3/4 full, place them in my freezer door and the top them off...  that does the  trick.  Overall I'm satisfied but believe the should be a bit less flexible.
