Love the mug, disappointed by the experience. I purchased a Navy Blue Ember Mug 2 in July 2025. Within 6 months, the gold charging contacts on the coaster broke off completely — the mug became a very expensive coffee cup. The mug itself is great, but a $150 product shouldn't have a charging coaster fail in under a year of normal use. Ember did honor the warranty and sent a replacement coaster at no charge, which I appreciate. However, the replacement is not the same coaster that came with the mug. They offered only a "compact version" — smaller than the original — and explicitly stated it is not the standard coaster. So the warranty replacement is a downgrade from what I originally purchased. On top of that, Navy Blue wasn't available in the compact version anyway, so I'm also left with a mismatched coaster on a premium mug. The support process added to the frustration — multiple follow-ups over several weeks, including an AI-generated non-answer, before a real person resolved it. Bottom line: great product concept, but the coaster durability is a real weakness and the warranty replacement process leaves a lot to be desired. If your original coaster fails, don't expect a like-for-like replacement.

Overall the product IDEA is great, but this product falls flat. The charging coasters go faulty after about a year. Poorly designed. The pins to charge the mug get stuck & won't charge the mug anymore. The mugs themselves also stop working after a year or two & no longer charge. I'd stay away from this company & go find a similar product elsewhere.

While it worked it was a fantastic product, but soon the enamel started to flake off and despite promising to replace my cup I waited for 3 months for nothing. Just got AI written responses and false information about my cup being on "back order". The cup was freely available to purchase from both the UK and US stores the entire time. What makes it worse is that I never expected to get a replacement, but they offered it to me, got my hopes up and then never delivered. TL;DR - great product, awful customer service.

Buy it on Amazon, don't buy direct Bought a mug upon request for a family member who later changed their mind. Great, there's a 30-day money-back guarantee (based in the EU). Unfortunately it wasn't that simple. It took several emails to get a return authorized, had to pay for return shipping (fair enough), and it took several emails again to get the full amount back. It was a huge hassle and therefore I wouldn't recommend that you buy direct from Ember.

The product has two major design flaws that make it a poor choice and a very poor value for the money: 1) It charges using two tiny electrodes sticking up from the base that make contact with the bottom of the mug when it is resting there. The problem is those electrodes don't hold up very well. My experience is that one of them got pushed down to the point where it won't make sufficient contact and the mug will not charge. 2) Notice how the base of the mug is rounded (and it is rubberized). If you have it resting on your desk to the side (or even right in front of you), if you knock it (which is easy to do if you move at all or reach for something) guess what happens? The mug tips over, spilling your beverage all over your desk soaking your work, your books...anything else in the way. What a mess! The customer service is customer no-service. The remedies they publish on their site are not working for me. As they suggested, I have "reached out" to them via email...three times. Repeatedly, no response. I have observed other competing products at a MUCH lower price point that do NOT have the design flaws just mentioned: 1) they use magnetic induction to charge the mug so you aren't dependent on tiny electrodes that don't hold up very well, and 2) the bottoms are very modestly rounded and the shape is more trapazoidal, if you will, so that if you knock it with your hand while working, instead of tipping over spilling all over, it just scoots. Both are superior design features. I bought the product because these guys were the first to market, and I thought that would make it the best. (Plus, I thought it looked pretty cool.) Experience has proven my decision to be a bad one. Knowing what I now know, I would not buy it again, and after about 24 months of use, will probably end up throwing it in the garbage.

Got ember mugs for my wife and I for Christmas. We had the best coffee experience of our lives for about two weeks. By January 5th neither of them worked any more. From day one we had issues pairing the devices, and would have to do it every morning until one day one one just quit connecting. About four days later the other one quit working. Not worth the money at all.

There is clearly a design issue with the lid as so many people are complaining and mine lasted only just over a week, before it was broken. For such an extremely expensive product I would have expected the lid to be made from something other than cheap china plastic!. If it was metal I think the problem would be resolved and for the money the lid lets the whole product down. So extremely disappointing and I DO NOT RECOMMEND purchasing until they fix the lid issue, which according to the reviews is the only major issue they have. I am very pleased with the Mug2 itself and it performs as stated, so very pleased with that aspect. That being said, my customer service experience was excellent. They were slow off the mark and I thought I was going to have a problem, but they asked for photographs, but responded very quickly and replaced the lid, which arrived in 5 days, which from the pacific coast of the USA to the UK I thought was excellent, so it has partially made up for my broken lid experience. I just hope it last longer than the first. One other thing I was extremely disappointed in was I wrote a review on their website and they changed it to suite them taking out the negatives about the lid and changing my star rating, that is just DISHONEST and have to ask can you trust a company that does this? I certainly do not and in fact I call it corrupt, manipulating customer reviews.

Got the Ember Mug as Xmas present and really like the idea of it. The mug works and keeps my tea at the desired temperature. Unfortunately I always receive a small electric shock when touching the mug while it's on its charging plate. 2 weeks ago, I contacted their support but never got a response. The company behind seems to have no customer support.
