Review on Set Of 4 Beasea Stainless Steel Insulated Cups - Stackable, Double Wall Vacuum Insulated, 10 Oz Metal Drinking Glasses For Kids And Adults by Jon Dugan

As a 16oz insulated cup, it's the smallest I've seen. The insulation aspect is not good, a great deal of heat is lost on all sides. This cup won't keep your drinks cold or hot for too long.I tested with boiling water. In 10mins, temp dropped to 170f and 165f (regular coffee cup). Both cup was too hot to hold. this mug couldn't get a temp reading on the side, the coffee cup was 157f.I just want something that won't sweat in the summer and won't burn my hands with hot drinks. I think it should hold up quite nicely over time. Air is too dry to form sweat for cold drinks, but will update if cup sweats in Summer. Under $7 a cup, still good value.
