We tried a bunch of different tumblers, thermoses, and a water bottle, and ultimately found the ideal ones.
The mug in the foreground has a really cool interface – to open the lid you need to press it at a certain angle with your finger, it clicks and shifts, and clicks back into place as well. The mechanism is well-crafted, operates precisely, doesn’t spill a drop, and it’s very intuitive to feel in the car which way it might pour when tilted, and of course, it’s easily visible whether it’s open or closed (these two flaws accompany most mug tumblers). A downside of this particular mug – compared to a thermos, it doesn’t keep the water boiling hot for as long as one might wish. And it seems it shouldn’t be washed in a dishwasher. Also, there were some old comments on Amazon about its unreliability, but probably the manufacturer has fixed all that by now.
The second, silvery one, is actually a thermos. Besides being the record holder in our tests for the time it keeps coffee very hot, it also has a cleverly designed lid. By pressing a button, a slit opens around the rim, and you can drink from any side. It holds up well in the dishwasher. Feels nice to the touch – like a cybertruck. The downsides – it takes an additional second in the car and some getting used to, to figure out by sight or touch whether the mug is open or not. This is already the third such item in a row. We periodically replace it when it wears out.
The other two bottles are for cold water. They are simply well-made, don’t spill when turned upside down, and instantly open a wide “spout”.
