Excellent heat preservation, sealed seal and no leaks, good for coffee preparation in home, office, garden or public places. But its size is too large, I would not recommend using it while driving
I've been blown away by how insulted it has kept my coffee (both hot and cold). I had the top on it, packed the car, drove almost an hour before opening it to enjoy it and it was the same temp when I put it in.
The 2-downsides: 1) The lid is separate, so if you are going for a walk or moving around, it is an additional item to juggle. 2) I had a small dent in the bottom of mine when I received it. I haven't dropped or nicked it yet, but that makes me nervous that it could dent easily.
I wanted a cup that worked with my aeropress and something that I could take with me and not have to worry about it spilling. It keeps my coffee hot and I can take it anywhere! It is really fantastic and so well designed!
Being at home having remote meetings, I always want a cold drink nearby with lots of ice. I normally have to be prepared for the sweaty glass with a coaster and paper towels. Not with the Carter Everywhere Mug! Sure, you might think it is your average travel mug. No, it is different because it is shaped like a glass rather than a skinny bottle. I love it in white and my husband has the black one. It is perfect for coffee or tea or a cold drink. The temperature won’t change during those hour meetings.
They sit in the cupboard as purchased from America and can’t return without the cost of the item in postage so it’s pointless returning. Had no idea it would be so big, chunky and heavy (purchased 12oz) and not fit in any type of cup holder, hand barely fits round it so it’s useless to us. It’s just a really badly designed product.
