Very good and easy to use. It is made of plastic and for this reason it loses a little in terms of temperature preservation compared to the regular lid. Nevertheless, for use within a few hours, it is just what you need!

I use it at the gym, on hikes, and at home.
Very good construction quality and very practical.
Secures perfectly, no leaks.
Possibly much more user-friendly than the original lid, but that depends on how someone uses it.

It is very practical and convenient, I recently got it and I am very satisfied. It fully secures the heat without any leaks, the handle is just right, and overall it is much more useful than the default lid.
