Review on Simple Modern Insulated Voyager Travel Food Service Equipment & Supplies by Isaac Simpson

. I have two cups; one for hot and one for cold (since coffee leaves a lingering smell, I just use my hot mug for this). I brew my coffee around 9am, it stays hot for about 3-4 hours and even around 3pm it's still MUCH warmer than room temperature. I have the best crushed ice at my job so I fill up my mug before I go. I fill the cup with water a few times when I get home and have half a cup of ice left over in the morning to add to my daughter's water bottle for school the next morning. Nothing was spilled at all, although I picked it up immediately. But the mug I use for coffee has the black flip top broken so it's definitely not leak proof anymore, but the coffee still stays hot. In general I am satisfied with the product, I would just like a new case for it. My sister bought two mugs and I will order one for my mother. Despite the broken lid I give 5 stars.
