Key Features Explained
The wide opening is intended to make filling and cleaning easier, and to allow ice cubes to be added. Although the lid is described as leak-proof when closed, that wording should not be taken as a guarantee against spills in every carrying position or condition.
The hot and cold retention times are stated figures, but no test conditions are given. Treat them as guidance rather than guaranteed results for every drink or situation.
What to Compare Before Buying
- Capacity: Check whether 500 ml suits the amount you need between refills.
- Insulation: Compare the stated hot and cold retention times with your needs, allowing for the unspecified test conditions.
- Design: Make sure the Periodic Table pattern is the design you want.
- Carrying: If packing the bottle in a bag, close the lid securely and consider how it will be positioned.
