Ember Technologies Arvostelua 

Just landfill tat. Doesn't connect, charging base breaks, can't replace the battery. Please don't buy, just think about the planet, no one needs this. Ember isn't a cool r&d Californian company, I think it's just trading bulk products from China.

Just got my mug for my birthday. The mug itself is fine, but using the companion app is a lesson in frustration to say the least. Like so many others, I have found that it continually disconnects. Sure, I can set my temperature and then just ignore the app, but the whole point of getting the ember is the precise control the app supposedly gives you. I'm thinking of having my daughter return the mug and getting a NextMug instead (which doesn't have an app, but is less expensive and provides 3 or 5 preset temperatures and also has a lid that helps it keep it hot longer).
Oh, and forget trying to install an update to the firmware. I have followed every option I've found that had worked for others except for the brute force method over the course of weeks/months. I even tried the official troubleshooting steps provided by ember support by resetting everything first and rebooting my phone. I can get the mug to connect, but it always disconnects when trying to update.

Received mug as Christmas gift from my daughter. It died after 4 months use. Wrote to company and complied with their request for model number, serial number, pictures of cup and bottom unit, etc. Sent me a second request for additional pictures of tiny connect fixture on bottom unit. Unable to comply. Very snide response from their PR rep. No support. I felt as though they were making fun of me.

I received this as a gift. This mug worked OK for me for awhile. I never messed with the app, just used it with the default settings. At some point, the paint started to chip on the bottom. To me, this presents a health hazard because I don't think ingesting paint chips is a good thing to do. I asked for a replacement, but received a run-around from customer service asking for pictures which I submitted multiple times. I would not recommend this mug to anyone.

Contacted them for the coaster pin issue. Was promised a replacement 2 months ago. Still waiting. Tried contacting them and they respond after more than a week each time promising its being dispatched shortly. Terrible customer service and terrible coaster charger.

Ember customer service sucks. They don't care, they are like weird robots who just tell you to keep warm. Yet another coaster pin issue and they have promised for 6 weeks to send another. They are as low as a company could get. I wouldn't ever buy this trash again.

As other reviewers have said, it is pointless having this mug as it never remains connected to the app so every time you try and use it you have to go through the whole searching and pairing process, which inevitably fails.

This is not a short term problem. I have had the mug for over 6 months and nothing has improved despite thousands of reviews which state the same issue.

I have many other devices connected via Bluetooth and never had a connection problem.

The only way to effectively use it is to get it set and forget about the app. This means you can't change the settings or preset temp.

One sole reason for 5* - Melissa in customer support. I had a mug that had started to deteriorate at the base. The support team knocked it out of the park in taking ownership of the problem and resolving. This is what customer service is all about.

Returned a travel mug as I wanted the base mug, they failed to provide proper return details and have sat on the refund for a few days now

It's nice coffee mug with a warming plate. If you're purchasing it to be able to use the app to keep it hot off the plate, especially if you have an Android device, do not purchase this product. Even the Ember website shows that they haven't done product testing on newer Android phones. I would understand if this were a brand new item but it's been sold for years at this point. And at a cost of $150, the customer should be able to expect a product that works as promised. Ember does not work as promised.

Received an Ember mug for Christmas. I don’t think I can go back to a normal coffee mug ever again… this thing is incredible. Usually, I’ll make an evening tea. By the time I’m done sipping on it, the tea would be cold. Not anymore! I’ve used this mug two nights in a row now. Each time, my tea stays the perfect hot temperature. The mug even syncs with the Apple Health app, so you can track your drink consumption vs caffeine and heart rate. I highly recommend the Ember mug!

I have had the common issue with one of the pins on the coaster staying depressed so it won’t charge the mug. A real design flaw and great shame as I will miss this mug.

The app is an abomination.

The fact that there are no physical buttons (on the base for example) mean that I have to adjust the temp from the app but it never connects.

No good excuse for this at this price point.

I love this mug, I’ve had it for 3 years and it’s always worked amazingly. What doesn’t work well is the charging coaster. It has two pins, and these just aren’t very fit for purpose. They seem to break easily, one ends up staying depressed and then the coaster won’t charge the mug. I have had about thee coasters now and always the same issue + It’s just happened again.
Surely there is now wireless technology that would work rather than having a pinned coaster. Especially as they clearly don’t do well around liquid, given the fact it’s a mug to carry hot liquid it seems rather silly.
Now you’re probably reading this and wondering why I gave 4 stars. And the reason I have is that the customer service has been exceptional. Once I email and send photos they have always got a new coaster out to me and it’s given the mug a new lease of life. Yes it’s a hassle when it breaks but I have the confidence they will sort it out for me & I love my mug, I enjoy every hot drink I have in it. I just really hope they sort out the charger issue!!

I am not sure why there are so many bad reviews here but I have 2 mugs and have had them for years. Just had an issue with one of them and emailed support. They got back to me within minuets and took some details and shipped out a replacement.

I am very happy with the products and the service

I want this to work SO bad. So bad, that I've purchased 3, thinking they'd eventually get it right (first purchase was when the company was new) Alas, they still haven't fixed the mug's issues - inconsistent charging, inconsistent connection with app, hit and miss ability to keep coffee warm. I am so sad, I give up. A pin on the charger is (once again) stuck in a down position/not charging. No more requesting a new charging base. I am done. :(

After a few months the mug stopped charging because a pin on the charger was bent — a common problem as far as I can tell. When I contacted Ember I found myself in a doom loop of robo-emails asking it I was happy with the service, but not a single one providing a solution or even acknowledging what the problem was.

Travel mug stopped working in the first year, customer service said it was out of warranty? Taking issue up with retailer.

Works really well if you keep it on the charger, but dies quickly if off the charger. Still worth it IMO if you like your beverages to stay hot!

I got this a gift from my mother. It literally lasted about 8 months before the charger stopped charging. Customer support was ready to replace it but due to my location they wouldn't mail a replacement or provide a refund.

On the plus side the cup itself is well made if you ignore the heavy heater at the bottom.

If you want warm coffee get a thermos; it will literally keep your beverage warmer LONGER.
