This thermocafe has a solid feeling twist top lid, you can feel confident that it won't come off or leak when it sits in your bag with your phone, tablet or papers. The lid requires only 2 turns to open or to close, so there's no guess work or holding it upside down to reassure yourself that it won't leak. I bought 2 colours of this Thermos, this red colour plus an aqua colour, they look really nice and don't scratch easily. As it's a Thermos you usually find that the double walls mean that this 500ml bottle is a lot bigger than other bottles, but this is not the case, the Thermos is surprisingly small for a vacuumed sealed bottle and it fits into car cup holders. I've never used the thermocafe for keeping drinks hot but it most definitely does a good job in keeping drinks cold for many many hours. So yes, a great little water bottle at a good price. I highly recommend it.
