Generally, the squares and diamonds are fine and do a good job. I wouldn't say that the spheres are very good due to the silicone not closing properly, and the result is a bit strange. The material seems correct, but time will tell

After one month of use, the silicone molds appear to be of good quality but probably not as sturdy as they should be, as they tend to bend when transferring them to the freezer. Also, you need to have an empty flat surface in the freezer because, precisely because they are not sturdy, they bend and water spills out. My freezer is always full, so it is difficult for me to make ice cubes, especially with the round ones. For now, the ice cubes do not smell like with other ones I have tried.

The round ones, of course, as you fill them, the water pushes the lid and inevitably leaves a small gap. The result is not bad and the ice cubes come out somewhat like Cronus :)

The square ones are the easiest to fill and transport. The lids close very well on the square and diamond shapes
