Review on 🔥 Ember Temperature Control Smart Mug 2, 14 oz, Black - App Controlled Heated Coffee Mug with Extended 80 min. Battery Life - Enhanced Design by Kimberly Cole

I think it's important for potential interested buyers to understand that you have to bear the return shipping cost, which is around $25. This company does not issue a return label acceptable to UPS, USPS, or FEDX. The mug won't keep the drink warm for more than 30 minutes, and it's only 12 ounces, basically a small cup of coffee. I think an 18 ounce mug would be better for us coffee lovers. The quality of the product seems substandard in my opinion, the price is around $130. I wouldn't recommend this to anyone.
