Keeps liquid hot for several hours. Very happy purchase!

This is a great product.

It works as advertised, iced drinks still contain ice 8hours later.

Shortcomings: you can't drink coffee from it within 2 hours for fear of burning yourself unless you make it with cooler water.

My third Stanley purchase. All brilliant. Long lasting well built product.

Solidly built, and does exactly as it claims. I winter camp and I make a hot drink last thing at night , to drink throughout the night, and it stays hot the whole time .
