Large volume
It fits in my stroller holder
It doesn't leak (only if you have a straw that doesn't have a sealing function)

Practical operation - can be used to drink through a straw or through a hole. When drinking through the opening or when closing, you do not have to pull out the straw, thanks to the rubber inside the straw can be inserted inside. No leakage when all openings are closed. Colour is very nice, just slightly purple. Overall, it has a good quality. For the money, really great

Leaking

nice design
the drink really stays warm
really does not fit in the car door (skoda octavia), so for us it did not fulfill its purpose, I bought it mainly for the car...

If the product had not arrived damaged( it was already unpacked) it would have been perfect. The end of the straw is rubber and the hole can be closed in height with a straw that slides in and pops out when opened. quality material and beautiful workmanship.

After reading the previous review I was worried about the quality of the straw, but even after putting it in freshly brewed tea it survived without a single injury. I'm satisfied.
seals great, no leaks
the tea stayed hot (when using a straw) from morning to evening

Straw made of plastic, which is built for higher temperatures. It bent in the cork tea and then crusted when it cooled. What good is a thermos if I can't put a hot drink in it?

Hello, thank you for your response. This thermos is actually designed for both cold and hot drinks. However, the straw itself is not made of a material that can withstand rapid changes in temperature. At the same time, it is not advisable to put the straw in a drink with a temperature higher than 90°C. We recommend letting the hot drink sit for a few minutes before putting the straw in it. From the next delivery, the straw will be made of acrylic for better durability. This is the same material as the top flange of the thermo cup, including the spout. Your feedback helps us to continuously improve our products. If necessary, please do not hesitate to contact us. Thank you and have a nice day, Ondřej - Alza expert
