Temperature-controlled clever glasses from Emmer have been rising in value over the past few years, most likely as a result of supply chain problems, but they now come in more hues, including some eye-catching metallics that cost a little more than common black, white, or orange glasses.

Ember produces wise mugs that fit your beverage of choice while keeping your beverage warm while sipping it in 6-ounce, 10-ounce, and 14-ounce sizes. Although it didn’t stay your coffee or tea hot for hours, the concept is to select your appropriate temperature from the companion Ember app for iOS or Android and maintain that temperature for your beverage for the first 30 minutes or so it will take to drink it lightly.

Although it does cost more, I prefer the 14-ounce type. The Ember allows you to sip a cup of joe like you would normally do, but only through a small hole in the top. A great covered drink with a major also keeps your tea hot ( and would be less expensive ).
