My old Ember was just not working....was very difficult to charge as one of the little prongs on the charging base was pressed in and would not pop back up. Kept watching both Amazon and Ember sites and finally saw a great sale on Amazon...thank you....so ordered right away. Received quickly and all is good...enjoying hot coffee again. Do have to say though that the Ember brand is very delicate and malfunctions easily. My old Ember needed to have charging base replaced - same prong problem and the mug needed replacing. Both were done by Ember without too much hassle....they were helpful. I treat my Ember very very gently following all the guidelines. Hoping that this one will last a few years without any problems. Do like and enjoy this product.
