This cup does what is says and so much more. The ones i got were in green and blue (one for tea and one for coffee). And mine were both without a handle.
I though that keeping it warm for 4 hours would mean that the content would be so-so after 4 hours, but it's still burning hot! So if I'm drinking it before that i need to let it cool for a couple of seconds before putting on the lid. But I prefer it this way, not the other way around.
Secondly - they WILL not spill. Upside-down shaking it full of content = no spill. I have had this on the side in my backpack and in my purse. Great product. I would really recommend it to everyone that is one the go and likes warm coffee and tea.
And i can't wait to use this for ice-coffee and ice-tea as well when the spring/summer arrives.
