I love these contingo autoseal bottles and travel mugs. But I just wanted to alert you to a problem my father had with a similar contingo autoseal water bottle. He had been continuously filling the bottles and not airing the cap and the cap was full of mould. This is common to all water bottles and is easily solved by taking the lid off and airing it overnight to refill the next morning. Run it through the dishwasher regularly (on the top rack). Fill it with a mixture of vinegar and hot water and leave that overnight on occasion (probably once a week would be ideal). If you have a fully stainless steel one stick it through the dishwasher at the same time as the top, but if yours is coloured, hand wash it in soapy water. Do this regularly - as often as possible - as mould is no good for anybody. While the problem is no doubt more prevalent with water bottles than coffee flasks, it could potentially be a problem for people who take the coffee flask to work and leave it sitting on the desk all day without rinsing it and then leaving the cap off for it to totally dry. But on the bright side, the autoseal drinking spout on these bottles is amazing. When you're ready to drink, press the button so the silicon seal inside releases and an ample supply of liquid will pour into your mouth. You can regulate the flow by how far you press the autoseal button in. I love these coffee flasks and they will keep your coffee warm, but don't expect it to keep your coffee boiling hot. They will gradually lose heat over time and if you start drinking your coffee or tea two or three hours after you feel that you will notice that it's not as warm as you may like. You can extend the time it will stay hot by filling the flask with hot water and pouring it back into your kettle and if you then immediately fill the flask with your coffee, it will stay much hotter for longer. But please note it will never stay hot for as long as a properly insulated thermos, but I properly insulated thermos does not have the benefit of the autoseal cap. It is a trade off and for me the benefit of the autoseal cap, far outways the downside. To be honest, most people will be using this to drink either immediately or in the next half hour on the commute to work and it's really not going to be a problem. When I have wanted to keep my coffee warm for an extended period I store it in my thermos flask and transfer it to this bottle for drinking - easy!Read full review

Love love love these mugs!! They keep your coffee hot for hours and the new improved lid is super easy to clean. The lid locks to prevent inadvertent spills and you can throw a full mug in your gym bag with confidence that it won't spill or leak a drop! And they keep on working even after being dropped - when full!

The reason I purchased EIGHT was I was so impressed with the original one, one of my friends ordered for me earlier this year. Now each of our children (older and younger) will have one :-)

It's a great thermos which holds a lot of tea and keeps it nice and hot! I don't think it's particularly cheap though but then I suppose you get what you pay for
