Query: makes nice, square cubes; easy to remove; no odors

I've been using these ice cube trays for several months now and love them. Contrary to some other reviewers' perspectives, I find that removing the ice cubes is simple if you simply push up on the underside of the ice cube tray and then grab that cube with your other hand once it's raised above the surface of the tray. (In other words, it's easy to remove individual cubes by pressing on them one at a time; I haven't tried simply turning the tray over and trying to remove all of the cubes at one time, so I don't know how well that works.) As to odors from either the trays or other items in the freezer, I haven't noticed a problem with this and I have a sensitive sense of smell.All in all, these are a great product. I also really like the way these cubes look in the glass -- square, clear cubes of ice.
