How we scored it
Our overall rating blends five weighted factors — materials & construction, everyday usability, durability & longevity, sustainability credentials, and value for money — with small category-specific tweaks (insulation performance for drinkware, grip and cushion for yoga, seal integrity for food storage). The sub-scores above are the rating; we then cross-check it against independent reviews from outlets like Wirecutter, The Guardian and Choice. If a spec, price, or long-term report changes, we update the record and re-score.
