The complaints on here are ridiculous. This product is amazing. I use my mug every day and have no issues. It keeps my coffee at the perfect temperature and makes my mornings so much better. The one time I contacted support with a question about the app they were quick to respond and resolved my issue immediately. I love this product and I have bought 2 others as gifts.

Purchased a mug for my husband. He charged it and connected it to the App. He didn’t like the idea of having to use an App for the temp control and we immediately decided to return it. They charged a $10 return fee and a few weeks later I received an email saying that because we turned it on (never actually used it though) we were not eligible for a return/refund. No word about if they are sending the mug back to us or what the plan is. Their return policy is ridiculous. Don’t buy one.

I had an issue with the battery on my mug which, after a year and a half of use, would max out at 80% capacity. I contacted customer support who replied promptly and offered helpful suggestions. When the fixes didn't work, they shipped me a new mug right away even though I was out of warranty. Very pleased with the service and a great product overall.

Had an issue with my Ember coffee mug not fully charging. Contacted Ember support and determined one of the charging pins wasn’t making contact. Ember provided a replacement charging coaster. Very pleased with the service. Highly recommended. CM

I've had the mug for four years and replace the charging coaster over 8 times. Done with it, what a waste of money

I ordered this mug. Hated it. Bluetooth lost connection repeatedly. Please don’t disregard these reviews. I returned with THEIR shipping label, per their policyNever got my money back. Now I’m out the mug AND money.

SCAM on return. I purchased 4 mugs on Black Friday 2025 as gifts I I returned 3 of them. The company received them on 12/16/2025. Today is 1/31/2026 and I have not received my refund. I have been in contact with them several times. I am told to be patient. ARE YOU KIDDING! I was told that returns would take 7-10 days. It has been over 6 weeks. AVOID this place. It is a SCAM.

Shocked to see all the negative reviews. In the past I had issue with my charger and they replaced it for me.. I’ve just had an issue with my mug and, despite it being out of warranty, they’re sending me a new one. Customer service was unbelievably fast to response - thanks Sweety!! Fan for life!!
