“It fits perfectly in my F-150's cup holder. I fill it with hot coffee at 6:30 AM, and it's still warm when I head home at 5 PM. No spills on my shirts thanks to the slider.”

THE AUDIT OF 146,000+ RATINGS
We parsed the reviews and compiled the core trends. Here is what real users say after months of daily carry.
Legendary for a reason
David T. • Denver, COI've owned budget cups before, and they always lose their vacuum seal after a few months. My YETI has been running strong for 3 years. It's the only cup I use.
Keeps ice in the hot sun
Emily R. • Miami, FLUsed this on the beach in 95-degree weather. Left it in the car for 4 hours, and when I came back, the ice hadn't even started melting. Worth every single cent.
Dishwasher safe is a game changer
Jonathan S. • Seattle, WAMost vacuum mugs say 'hand wash only.' Who has time for that? YETI goes straight into the dishwasher. The color hasn't faded one bit.
MagSlider is perfect
Brittany H. • Chicago, ILIt slides smoothly and holds splashes when I hit bumps in my car. Super easy to pop off and wash. Extremely satisfied.
Not 100% leak proof, but great
Robert P. • Phoenix, AZNote that if you flip it upside down, the slider can drip a little, as YETI warns. But for standard cup holders and splash protection, it's absolutely stellar.
My favorite gift
Amanda C. • Boston, MAI bought three of these as gifts for my family, and everyone uses them daily. The black color looks incredibly sleek and professional.

COMMUNITY QA
Based on customer audits and temperature tests, the YETI Rambler 20 oz keeps drinks cold and ice frozen for over 24 hours. For hot drinks, it maintains piping hot temperatures for 6 to 8 hours, and drinkable warmth for up to 12 hours.
YETI's premium price reflects its over-engineered build. It uses thicker 18/8 kitchen-grade stainless steel than budget alternatives, a specialized double-wall vacuum seals that doesn't leak vacuum over time, and a magnet-driven lid that doesn't wear out or break.
Yes! The double-wall vacuum insulation keeps carbonated beverages and beer frosty cold until the very last sip, and the stainless steel body is non-reactive so it won't retain any residual tastes.
