Very good thermos. It doesn't leak, which is the main thing. Terrific flexibility with the variety of lids. The handle on the lid was something I didn't know I needed and turned out to be very useful.

It is exactly what I was looking for, a thermal cup with a straw and a large opening for ice cubes, as I drink fr. espresso all year round. Quality construction, nice materials, it gives off a premium vibe. As for the negatives, the first one is purely subjective, which essentially bothers me, it is the size of the straw, which is thicker but it is expected for better flow, and that it doesn't seal well enough from the straw when it is closed, not something tragic to take away its 5/5.

I have purchased the largest size with 750 ml. Very convenient that it has 3 caps and a cleaning brush for the straw. The issue I have, however, is that the water cap leaks. The other two are fine. That's why I gave it 4 stars.

Very good thermos, it does exactly what it promises. It keeps the coffee cold for more than 5 hours. It's worth every penny until the last dime!
