I recently bought a Waeco 41 litre Cool Ice Box and used it on Christmas Day 2019 along side my older Evakool 64 litre Ice Mate , as a rough comparison on ice retention they were on par , with the Waeco holding ice slightly better , both boxes were prepared , pre cooled and iced on Christmas Eve .
The only minor concern I have with the Waeco is the screw in drain bung not tightening firm enough and may possibly leak but nothing that some white plumbing tape on the threads cant fix , otherwise it does a good job

Purchased a Waeco Icebox (41 litre) on a recent holiday to save purchasing ice for the esky on a daily basis. The "lcebox" works great and can keep items cold for 3-4 days, great for camping or caravaning. The icebox is robust and can be secured easily in the back of the ute.
