Zojirushi Stainless Steel Mug Black
Score: 69/100
JoyJolt Savor
Score: 71/100Rankings
JoyJolt Savor mugs are double-wall insulated glass espresso cups that keep beverages hot or cold while showcasing the drink through clear glass. Their glass construction makes them prone to breakage and the exterior can become slippery when wet. Ideal for espresso enthusiasts who value style and temperature control.
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.
“Perfect size for Nespresso or double espresso shots”
“Love the look, shape, and content visibility”
“One user broke two within days, another noted fragility despite liking them”
Professional reviewers commend the JoyJolt Savor mugs for their elegant double-wall borosilicate construction, which delivers strong thermal shock resistance and maintains drink temperature without condensation. They appreciate the clear glass that showcases espresso crema and note the convenience of dishwasher, microwave, and freezer safety. However, they also warn that the glass is inherently fragile and the limited warranty may not fully protect against breakage.
Everyday users overwhelmingly praise the mugs for their perfect espresso size, visual appeal, and the way they keep drinks hot without burning hands. Common complaints focus on fragility, with multiple reports of mugs breaking shortly after purchase, and the slippery surface when wet, especially during washing.
