Don't over tighten the screw top as it can pull the flip top away from the mouth piece, that why I've knocked a star off, it would be better if these two pieces were better locked together. You need to own the cup to understand what I mean but it does clip back together and works really well.
I'm gladly surprised at how long this mug can keep the drink hot. I tested it twice before writing a review. Once I started drinking my latte 4 hours after making it, and it lasted me hours of hot sipping. When I tested it again, I started drinking about an hour after making the drink and it was a bit too hot, actually. I decided to be more careful with how hot the drink is before I pour it into the mug. I had to wait a while to be able to drink it.
The only thing I didn't like about this mug is one aspect of the design that could be improved: the lid shouldn't open to the top of the drinking area, because it touches the nose/forehead area when the drink is finishing. It would be better placed on the side, due to the drinking movement direction. However, I still totally recommend this mug, as it definitely keeps the drink hot/warm long and doesn't demand another cup.
As regards its thermal retention properties they are, on a short timescale experienced, very impressive. First time out it was filled with cold water and a reasonable number of ice cubes. 32hours+ later there were still sizeable ice cubes (@ 1cm) still rattling around in the water. On the hot side we have not been willing to leave a drink too long but it is too hot to drink quickly some 8-10 hours after filling which is more than enough for what we would normally need.
This is the first that we have purchased but I expect that it will become a regular item to give away as useful presents and we will be getting more for use in the home environment. 5* very well deserved!
I have only had it for 1 week so will update if anything changes. But so far, so great!
