I’ve had mine for two weeks and the double-wall steel really does keep my coffee scalding hot through a full morning of meetings. The patterned exterior is also grippier than I expected, which is a nice bonus on my commute.

The 500 ml size is perfect for my gym bag, and the pattern adds a nice grip so it doesn't slip out of my hand. My water stayed cold for my whole afternoon hike, which is exactly what I needed.

Keeps my iced coffee cold all morning, even after sitting in a hot car for a few hours. The patterned exterior is nice and grippy, though the lid could seal a bit tighter—I get a tiny drop on the threads sometimes. Still, solid for daily commutes.
