bubba Classic Stainless Steel Mug with Handle Black, 52 fl oz.

keeps my drinks COLD no leaks around the lid or anything only bad side is no machine washing i must hand wash it

Nearly at 24 hour thermal cup. I stayed nearly 24 hours, because exterior temperatures and the level of contents inside constantly change in volume, etc. Exterior temperature does not reflect interior temperature while use. Dishwasher, friendly or hand wash. The only thing I would change about this cup, is either The drinking lip size/design or include a straw. My husband isn't over the road driver; he refills this cup on a daily basis. Uses it while driving. Without the straw, that we added, it's impossible to use while driving and being able to see the road. Adding a straw, he is able to keep his eyes on the road and drive. We also have a couple at home, straws, added, reduce any potential mouth, spills, etc. Due to health reasons, I have to keep track of my fluid intake. Knowing the quantity within, unlike having to guess with a regular house glass – is beneficial to me. On average, I filled the cup with ice and add my drink a choice. I do not need to refill either the ice nor the drink until the following day.
