- The new Mug 3 lets you change the temperature with the button on the bottom of the mug, without opening the app. Each press raises the temperature by 5 degrees. The mug cycles through five preset stages, starting at 125 degrees Fahrenheit and going up to a maximum of 145 degrees Fahrenheit.
- The original author said they used this button most at night in bed during testing. However, they also noted a drawback: because the button is on the bottom, you have to tilt the mug while holding a hot drink and press it firmly.
- In the app, you can connect to the mug over Bluetooth, choose presets for each drink, or set a temperature yourself. Ember's recommended settings are 136 degrees Fahrenheit for black coffee, 132 degrees Fahrenheit for green tea, and 142 degrees Fahrenheit for lemon water.
- The original article reports that the mug can keep its temperature for up to 3 hours on a single charge. The sliding lid is designed to reduce spills, and it is dishwasher safe on the top rack but cannot be used in a microwave. Prices are 10 oz for 129 and 14 oz for 149.
O: Useful for someone who keeps their phone away and sips tea in bed at night, when they want to raise the temperature one step at a time with the button on the bottom of the mug.
X: The original writer found the bottom-mounted button uncomfortable, since you have to tilt the hot mug and press it firmly, so you should check the actual feel yourself.
