My husband uses his 14oz Ember mug every morning for a single, carefully crafted cup of coffee. He recognized immediately that both the temperature and battery life were extended when he used the lid.
This lid is ideal for my life as a mom. Prevents spills when I get bumped by little bodies - and helps extend the battery on my mug by holding in more heat. This is an excellent addition to my Ember Mug
I’ve purchased two of 14oz sizes. One as a gift and one for myself. Both are used everyday. They really do keep your beverage hot longer. Besides, making sure you keep every last yummy drop in the mug or your mouth. The lid comes with three different color slides. Definitely buy one today.
