This is an all-day plus cooler. I pack my lunch (plus snacks in the tray) and a quart of sweet tea around 5:30. Snacks are chilly at 9:00, lunch is cold at noon (frozen entrees are still frozen solid) and the sweet tea is still icy cold at 2:00. When I head home, the ice packs are still 80% frozen.
This cooler could keep whatever you want at whatever temp you want, for as long as you want.
The tray is a good size, and the lid storage is big enough for my badge, wallet, keys, mints, and anything...
