I love this mug. Provided you make sure that the lid is on properly, you can chuck this in your bag and not worry about leakage. I've used it on the train, tube and in the car, and it's fab. I got a couple as a gift and was so impressed that I've bought this one as a present for someone else. They go in the dishwasher too. Highly receommended.
I am more than satisfied with my purchase of the Brugo travel mug. It has a nice look, preserves each and every flavor of your coffee, and keeps it hot. The cooling chamber allows you to cool your coffee down instantly, which is a brilliant feature. My friends and family envy me for my possesion of this item! Everyone seems to want one, and they'd be making a great choice if they were to buy one. Couldnt be happier!
Overall a bit of a disappointment. While the concept is good and it sort-of works, it has a few flaws that prevent it from delivering on its promises.
As others have remarked, the sip-chamber really is too small, and filling it with liquid is too difficult. It takes a real knack and even once you've mastered it you'll still be swigging lots of air out of it.
As a travel mug it's pretty lacklustre. Despite solid construction it just doesn't keep drinks warm for very long - an hour, at most. You can't rely on it to keep your drink hot if you get called away for a while. Possibly a steel inner chamber would help here, but currently it's just double-walled plastic. Which, as has also been mentioned elsewhere, doesn't taste very nice - however that's a shortcoming of all travel mugs, and I think it tends to disappear after enough washes.
It's a pity because the idea is great and it's so close to being an excellent product. Unfortunately, as it doesn't fulfil its key selling points, I wouldn't recommend it.
