Abstract: The manner in which you use this cooler is you first remove the lid, then remove the inner tray. You then add ice (as much or as little as desired), water (enough to cover ice), a hand full of rock salt and the desired beverage containers. If traveling reinsert inner tray and lid and that's it, But if you are where your going and you want a drink fast just simply mix water with your hand and set timer to Cold, Ice Cold, Arctic Cold, or Liquid Ice and when bell rings your drinks are ready. You can also reverse the lid and put ice and drinks in it as a serving cooler. The inner tray has four equal compartments for storing cold foods or for serving from. The Timer is also a great tool for grilling or as a reminder, when set, to keep an eye on the grill.
