When I bought it, I thought I was spending quite a lot for a water thermos. I have had it for 1.5 years and with relative care, it hasn't suffered any damage. From the first moment you hold it, you realize its quite high-quality construction. As for temperature retention, I have to say that in the summer with 10 ice cubes and at room temperature, you could feel the ice cubes for 72 hours. Yesterday afternoon, I forgot it in the car under the sun... The next morning, it still had ice. I consider it to maintain a good temperature. I haven't tried hot drinks. Overall, I consider it a good choice.

I have been using this specific Camelback thermos series for 10 years now. Recently, I bought the 1.2l one and the quality seems exactly the same as the first ones. The magnetic cap is very helpful. The water flows correctly, due to the curved surface on the mouthpiece. Cold water, with 30 degrees outside and the bottle exposed to the sun all day, at least for 14 hours.

I have had it for over a year....
I bought it with the logic of quality construction, influenced by reviews I read in general.... When I received it and started using it, it did not perform well. I spoke to the store where I bought it and to their credit, they told me to send it to them for evaluation.... They replied that it seems to be working fine and that there is no internal damage or general malfunction.... They advised me to put ice cubes in cold water to bring down the temperature completely, which will help maintain it..... (What kind of thermos is this that I have to put half an iceberg inside to keep it and it doesn't hold the temperature from the beginning... what can I say, I don't know....) After many attempts and patience, I conclude that it is not good at all.... It keeps the temperature cold, but not for the 12 hours they claim.... In the indoor space where I work, it has tap water temperature at noon....
