Cold Retention Test
Ice water was used to evaluate how long beverages stayed cold under daily use conditions.
Cup Holder Compatibility
We tested each mug across standard car cup holders and travel pockets for fit accuracy.
Cleaning & Maintenance Evaluation
We analyzed dishwasher safety, lid complexity, and gasket removal for cleaning ease.
One-Hand Operation Test
Lids were repeatedly opened and closed using one hand to simulate commuting scenarios.
Durability Assessment
We evaluated scratch resistance, seal integrity, and drop performance.
