Mongdio Self Stirring Coffee Mug Review
The short version
A cheap, honest stirrer with a temperature readout. It tells you your coffee is going cold; it cannot do anything about it.
Good for
- ✓ Tight budgets
- ✓ Thin drinks
- ✓ Desk use
Not for
- ✗ Thick shakes
- ✗ Slow drinkers
- ✗ Travel
In use
Double-click and it spins. Sugar and creamer vanish, and the readout is genuinely useful for not scalding yourself on the first sip.
It is also a running commentary on the problem: 158°F, 141°F, 129°F. By the third number the drink is a chore.
Where it runs out of road
Thicker protein powders defeat the small motor. You end up finishing with a spoon, which is the exact task you bought it to avoid.
For a few dollars more than a cinema ticket it is a fair purchase. It is not a replacement for a heated mug.
