Review: Thick Vacuum Insulation, Light - My first impression with the flask - light. The material used feels thin, but the space or thickness of the vacuum is thick which makes its insulation effective. Rubberized bottom, two screw caps, finishing is fine but a bit worried that it can scratch easily. Overall, a good flask and serve its purpose.

### ⭐⭐⭐ It's fine.

Don't expect the same temperature 24 hours later. It's okay. Probably not exactly as marketed.
