Rated 5 out of 5★ by repeatbuyer447 Simply put, I'm impressed. I bought this for my car which holds a lot of heat (black exterior and black interior). At first I was inclined to get a Stanley thermos. I saw the 20oz Bubba for less than half the cost. I tested it out as soon as I got it home. Tested this thermos in the best conditions on a hot summer day here in Houston, TX. I filled thermos with ice and tap water. Then placed in inside the car parked in direct sunlight. I checked it after 6 hours and sipped ice cold water. And checked it again after the 24 hour period. Water was not refrigerator cold but COLDER than room temperature! 07/29/2013
Rated 5 out of 5★ by nicknamesareassanine Best Mug I've ever owned. My girlfriend got me a new travel coffee cup for Christmas this year and I have been super impressed with its ability to keep coffee hot. I decided to go super nerd tonight and see just how well it worked outside. It started with water at 178 degrees when I set it outside in 22 degree temperatures. 6 hours later the water was still 105 degrees, and it had been below 10 for the last 3 hours it was outside. For anyone needing a good travel coffee mug, this is the one. 02/06/2014
Rated 5 out of 5★ by Fitastic Love it. It is rated for 24 hrs cold. Put it to a 15 hr. test and it still had ice water.That is long enough for me. 07/14/2013

Rated 4 out of 5★ by JEDmyBoy Love the way it keeps my coffee warm for so long. The only problem I have is with the seal. I have several and one leaks when I attempt to drink. Would like to get a new seal. 03/12/2014
Rated 5 out of 5★ by yoster Great Travel Mug!! Very pleased with this mug. No leaks and kept my coffee hot for hours. I poured my coffee in the mug at 4:15, and at 9:00 it was still hot. Fits in my car cup holder too! 04/07/2014
