What Plungers Say
Holds cold way longer.
Way better insulated than the stock tank I was using. My ice actually lasts now instead of melting by lunch.
Built for real winters.
Been running it outside through November. The walls are rigid and it hasn't budged. Feels like it'll last years.
Paired it with a chiller.
Started with ice, added a chiller later — hooked straight up, no issues. Packs down when I need the garage space.
