Retention figures on any vacuum bottle assume a full bottle, opened rarely, at moderate ambient temperature.

Buy it if: Couples and small families cooking for two or three, on gas or induction.

Buy it if: Anyone wanting genuinely cold water through an Indian summer day.

Avoid it if: Anyone counting grams -- 440 g empty is heavy against a plastic bottle.
