I was lured in by the beautiful design of the Chilly's Series 2 coffee cup. It is a thing of beauty! I was able to pick 3 colours of my choice. However once in use it is very disappointing. The open/ close method is tricky?stiff and the hole very small to drink out of. It ends ups dribbling down the side and down my chin. As far as I can see I have to uncrew the whole top to drink easily. Also the drink is not warm for 4 hours.. much less. I assume now I have used it I cannot return it. Save your money. It is a poor design for something that is meant to be an upgrade. All other Chilly's products I have bought have been brilliant
