I recently bought a Waeco 41 litre Cool Ice Box and used it on Christmas Day 2022 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.
