I would definitely buy it again, it has saved me quite a bit of money during my vacation.
I had cold water all the time!

5 stars for the bottle. It is very good and keeps the temperature. Don't think about it. I forgot it one day at the beach, and the next day when I went back, it was still cold.
Now as for the lid, due to the many moving parts it has, it tends to collect dirt. Especially on the one (gray) that I have for putting amino acids for training, it collects a lot of grime and is very difficult to clean, so I will go back to the classic screw-on. Even on the one that I only put water in, it collects dirt. Of course, it's good to clean it from time to time, I just mention it.

Good material. Bad packaging. Be careful if you use a straw, do not tilt the thermos.

Excellent. I've had it for a year now and it has been very convenient for me. The diameter is a bit large, of course, but it doesn't slip in my fingers.

I have bought it for my little one for summer beach and walks and activities a little heavy for her to hold it alone but it maintains its temperature well difficult to clean if the mouthpiece has been ruined by food!

While it is quite a quality product, as negatives I would first say that it does not have a lid to protect the mouthpiece from the straw, so in order to open and close it, you have to directly hold the mouthpiece, and secondly, no matter how tightly you close it, there is a small leak in the head and I consider that because of this, the initial temperature of the liquid is not maintained 100%.

Very good temperature preservation. Even ice cubes remain intact for hours before melting. The downside is that there is a small leakage from the top (straw). Also, poor construction both in the collapsible straw inside and in the corresponding collapsible brush (which broke on the first use).
