Score: 69/100
Zojirushi SM-SA36BA
Score: 70/100Rankings

The Zojirushi SM-SA36BA 12 oz mug combines vacuum insulation with a leak-proof flip-open safety-lock lid in an ultra-lightweight stainless-steel body. Its main limitation is the lack of published temperature-retention data and a relatively small capacity. Best for commuters and office workers who prioritize portability and spill protection.

The Zojirushi 16 oz stainless-steel travel mug offers strong vacuum insulation and a secure safety-lock lid in a compact, lightweight package. Its drawbacks include a heavier-than-advertised feel, a narrow mouth opening, and the need for hand washing. Best suited for commuters and office workers who prioritize heat retention and spill protection.

Products in the top-left offer the best value (high score, low price).

Professional reviewers commend the SM-KHE48 for its impressive heat retention, compact size, and reliable safety-lock lid, noting that the SlickSteel® interior adds durability. However, they criticize the inaccurate weight claim and the limited 16 oz capacity for extended outdoor use, and they point out the small mouth opening as a usability drawback.
Everyday users praise the mug's ability to keep drinks hot or cold for hours, its sturdy construction, and the spill-preventing lid, while repeatedly mentioning that the actual weight feels heavier than advertised and that the 16 oz size can be limiting for long outings. The narrow opening and limited color choices also surface as common concerns.
