16Oz Temperature Control Smart Mug, Self Heating Coffee Mug LED Display, 180 Min Battery Life – Hot up to 149℉ Fast Wireless Charger Base Improved Design coffee serving sets mug(16oz, Orange)

I bought a few to test as potential company swag, and one was faulty after a couple months of use. I contacted their customer service and they were very responsive, professional, and sent me a replacement. Trust-worthy team and brand.I also have Ember, but I like VFZO much better since it shows the temperature, you can directly control the temperature without using the app, and also comes with a wireless charger.
