Very cool looking cup

The style of this cup is really cool, I have never seen another cup like this before.  I love how  lightweight it is and the lid actually stays in place, unlike some of my current cups.  My only complaint is that it doesn't seem to keep the hot drinks as hot as I'd like which is why it received 4 stars instead of 5.  Cool drinks however, seem to stay cool and crisp so no complaints there.  Overall, a pretty good deal and sure to be a talking point on the design, like I said very cool looking :)
