- Fill and watchability: An integrated funnel or transparent lid helps monitor water levels while filling or freezing.
- Durability and maintenance: Durable trays resist cracking; ensure compatible freezer space and storage.
- Multi-use flexibility: Some sets include both spheres and cubes, offering experimentation with infusion and flavoring opportunities.
- Price-to-value: Compare sets by the number of molds, size variety, and included features to maximize long-term value.
