This cup is worth the money! I now have him for over half a year and use it almost daily. He has never leaked, no matter what position it is in my pocket or stands. He holds the promised four hours hot and thus ensures that I still have warm coffee during my lunch break. If you feel a rapid drinking pleasure, should be careful to drink because of tea or coffee is not cooling as quickly. But Contigo has a drinking cup, which holds only one hour warm, which is then determined the ideal mug for all "Quick-drinkers." The cup is not dishwasher-safe, but the drinking cap I put regularly in the dishwasher, which has not harmed him so far. I'm super happy with this cup, have already recommended and has presented him.
