Product review (5 stars): Nice and Big eye cubes
This tray produces nice and big ice cubes that melt slowly. They make for good whisky. I prefer them to whisky stones, and these big cubes are more appealing visually.

You can however, expect some white portions on the top of the ice caused by bubbles. This is normal, but not the most visually appealing. So solve this, you will search youtube how this can be done using a small insulated cooler box, but before you get there, you find need to be able to make huge ice cubes that are easy to remove (important). That is where this tray comes in. The tray is a very soft and flexible silicon allows you to easily push the ice cubes out by pressing the bottom of the tray.

I am very happy with my purchase
