Product review (5 stars): Easy
I saw large cubes like these used in certain cocktails at a fancy restaurant. I decided I'd like to copy the look at home, and I gave this tray a shot. I've been very happy. This was my first encounter with a silicone ice tray, and I am a big believer. No more twisting hard plastic trays, and hoping the plastic doesn't snap or the cube doesn't get crushed.  With these, just firmly push the cube from the bottom of the tray and it will pop out.  Note, I've found using filtered water (from my Brita pitcher) results in clearer ice cubes.
