Works well but..
- Familiarity: I've put it through the wringer
These are great in that they work well for exactly what I wanted them to do, which is hold hot or cold liquids at the right temps and to finally have a lid at this volume/size. Durable, attractive, and useful.
Just like the other reviewer I was truly bummed to see that they do not stack with my 4 others of this size, that I already owned from Hydroflask, and that the lid does not work with the previous version either.
