Great for camping trips

Took two of these on a 3-day hiking trip. They fit perfectly in our cooler and kept the meat and dairy safe. One star off because they are a bit heavy to carry when fully frozen, but that's expected.

Commercial grade quality

Bought a bulk set for our small catering business. They withstand constant washing and freezing without cracking. The temperature retention is consistent, which is crucial for food safety compliance.

Essential for outdoor events

We use these in our portable air cooler for outdoor wedding setups. They keep the air circulating cool without the mess of melting ice cubes. Very durable construction.

Perfect for my street food cart

I use these in my mobile drink station during summer festivals. They keep the ingredients fresh for the entire 10-hour shift without melting into a puddle like regular ice. Highly recommended for vendors.

No more waterlogged coolers

The best feature is definitely the leak-proof design. I no longer have to drain soggy water from my cooler after a day at the beach. The cooling power is impressive compared to gel packs.

Solid performer

Does exactly what it says. Freezes solid and stays cold for a long time. The handle could be slightly more ergonomic for carrying multiple units, but otherwise a great product.

5 FAQ

Q: How long does it take to fully freeze in a home freezer?

A: In a standard home freezer set to -18°C (0°F), it typically takes between 6 to 8 hours to reach maximum solidity and cooling potential.

Q: Can this be used directly in contact with food items?

A: Yes, the outer shell is made from food-grade PE plastic, making it safe to place directly alongside fruits, vegetables, and packaged meats in a cooler.

Q: Can I stack multiple units in the freezer to save space?

A: Yes, the flat rectangular design allows for efficient stacking in freezers, making it easy to store multiple units without taking up excessive space.

Q: Is this compatible with standard evaporative air coolers?

A: Absolutely. The dimensions are designed to fit into the water tanks or ice compartments of most commercial and residential evaporative air coolers.

Q: What happens if I accidentally drop it while frozen?

A: The high-density plastic is impact-resistant and designed to withstand drops even when frozen solid. However, avoid dropping it on sharp objects to prevent punctures.
