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 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.

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.
“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”
