Score: 71/100
Dowan 15oz Coffee Mugs Matte Gray
Score: 80/100Rankings
The Dowan 15 oz mug set combines a generous capacity with a splash-resistant lid and cork bottom for added stability. However, the lid is not completely leak-proof and the mugs require hand washing, which reduces convenience. Best for users who value anti-slip protection and a secure lid over portability.
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.
