Ordered a series 2 bottle and coffee cup and then saw these reviews and thought what have I done, especially the coffee cup and the leaking issue. I needn't have worried. The coffee cup doesn't leak for me and keeps my drinks hot for about 2 1/2 to 3 hours with the hole open. The top Tis quite stiff before you put a hot drink in it but i was warned about this. They also feel nicer in the hand than the Sho bottles. The only criticism was the box they were packaged in. It was very thin and was partially open also a small dent in the water-bottle lid but it is a small dent and I can live with it. I have since ordered another coffee cup for my husband.
