Review on Stanley Classic Vacuum Bottle 1.4L (Matte Black) - Superior Insulation for Long-lasting Hot or Cold Beverages by Franciszka Mazurek ( ᠌

Maintains temperature by losing 1°C per hour. Measured twice with a Testo 905-T2 contact thermometer. It seems to me that this is a very good indicator. The workmanship is top notch. The cork and lid twist and unscrew without jamming and distortion. I am satisfied with the purchase. Some pros: Convenient folding handle. Good volume. Holds temperature very well. Different cons: There may be a lack of an established mesh in the neck, but this is not critical.
