First of all, the novelty of this mug is something I really don't think could wear off, whether you're buying this for your coffee loving self, or as a gift to another coffee enthusiast.

Although a little small in volume for those of us who enjoy a large cup in the mornings, the insulation keeps it hot for ages, long after a normal mug would've gone cold. This, combined with the silicon lid, make it great for morning traffic and other times your mug may be left unattended for a while.

I can't yet comment on the durability, but it feels solid enough to last as long as any other mug.

And again, the design is just brilliant. I can't stress it enough.

Bought this for my dad for his birthday and he loved it. And this thing actually works and keeps your favourite hot drinks warm for a long long period of time!

I was really excited about this cup, yet found it horribly disappointing, was expecting it to be a bit bigger, and the lid is so flimsy that its not the easiest thing to get on, plus no “air” hole in it makes it harder to drink from too.
