In the first few days, the logo had come off and the bottle had been damaged. After approximately 6 months of use, it no longer maintains its temperature and half of the bottle has turned gray from wear and tear.

On the first week, without any reason, it didn't keep the drink warm at all. I thought it was defective (something that happens to anyone) and it was replaced by the company, but the second one had exactly the same behavior in just a few days of use, it no longer has any durability. Fortunately, a refund was made.

It broke within 2 months, tragic.
I have it to make baby formula.
After 2 months of use, it stopped keeping the water warm

Σκούριασε εκεί που βιδώνει το καπάκι την επόμενη μέρα.....απίστευτο.Κρίμα στα λεφτά. Αν και κρατάει θερμοκρασία. Ελπίζω να μη βγάλει σκουριά και μέσα.
