Review on Civaza Ice Cube Tray - Stackable, BPA Free, Flexible, with Lids - Set of 2 Silicone Ice Trays for Whiskey and Cocktails (Blue + Green) by James Wing

Well, they're small and need constant refilling if you use a lot of ice. The lids don't fit the tray exactly (they're silicone and the edges don't seal), but you can place them on a water-filled tray to stack the two on top of each other before they freeze. But many other reviews are wrong. You don't have to wait to release the dice. And don't try to bend or twist the tray to loosen them - it won't work. The easiest way to get the ice out is to push it out from underneath. One finger is all it takes to slide the six-sided cube up high enough to grab it. A regular glass (8 ounces) of soda requires about 6 cubes. These shells will not break like hard plastic shells. Also, quickly fill the entire bowl, then tilt to pour out excess water. Trying to fill every cell takes too long. If there is too much water and some of the cubes are frozen, the stab and remove method will still easily crack the connecting ice. Conclusion - easy and fun.
