A: Honestly it comes down to quality. This is an expensive item but the build quality and finish are exceptional. Especially the finish they used on the mug. The finish is like metal silk, so smooth.

A: To keep your coffee warm and at that exact perfect temperature. Some people care about it more than others. Definitely a little excessively priced but a really thoughtful gift for the coffee or tea lover with distracting kids not allowing them to finish their coffee quickly.

A: Buy it if you want to keep your coffee or tea warm. Better then drinking cold or room temp coffee

A: Yes there is slight staining that I have been unable to remove

A: YES. Mine has a dark coffee stain on the bottom of the mug that won't come off. The coffee stain along the sides comes off if I put a little bleach in the water and leave it for a minute.

A: No, it's recommended to hand wash the mug to maintain its quality and functionality.

A: The mug is made from ceramic and stainless steel, ensuring durability and insulation.

A: The battery lasts for 1.5 hours of continuous use before needing a recharge.

A: Yes, it connects to both iOS and Android smartphones for temperature control via Bluetooth.

A: The mug can maintain temperatures between 120°F and 145°F, allowing for personalized enjoyment.

A: The Ember Mug (10oz) has an internal lithium battery which can power it off-coaster for approximately 90 minutes. The included charging coaster does require a power adapter (also included) to allow the battery to charge. The Mug can also be left on the coaster between sips for all-day use.

A: Hi Dela, thanks for your interest. First of all, we ask that you please do not microwave your Ember Mug. The Ember Mug 2 is an electronic device, which should never go in a microwave. As with all electronics and metals, it may result in a fire when heated up in the microwave. Doing so will result in permanent damage to your Ember Mug 2. Because the Ember Mug is designed to keep hot beverages at your perfect drinking temperature, it is recommended that you always pour liquids that are already hot to ensure the Mug works as expected and you get the most out of its battery life.

A: Hi Sannie, this is a great question. One of the things that makes the Ember Mug so special is that it can be enjoyed on your coaster or away from the coaster thanks to the internal lithium battery. The amount of time required to reach your perfect temperature will depend on a number of different variables: the temperature setting of the Mug (ie. it will take longer to reach 135°F compared to 145°F), the environmental conditions (Your mug will cool faster when used outside on a cold day vs. during a hot summer day), and the pour temperature of your beverage (fresh brewed hot coffee will take longer to cool than a pot of coffee that has cooled down). I am sorry we can't give you a more concrete answer, but the amount of time can vary wildly depending on these factors.
