What to Look For
| Feature | Why it matters |
|---|---|
| Capacity | Check the stated ounces, because oversized means different things to different makers |
| Insulation | Double-wall steel keeps drinks hot or cold far longer than ceramic |
| Lid | A sliding or sealed lid cuts spills but can be harder to clean |
| Handle | A wide handle is easier to hold when the mug is full |
| Fit | Measure cup holders and under-brewer clearance first |
