I’ve had this product for a week and I love it I use it several times a day. However, the mug is already having some issues. At least once a day I have issues reconnecting the mug to my phone. I have the latest software, but when I open the app it says the bluetooth isn’t turned on. If I open the settings, the bluetooth option will say I’m connected to my ember mug.... I’ve already had to reboot the firmware and restart my phone numerous times.

With regards to the actual product specs: a one hour utility time for a one-and-a-half hour charging time? That’s ridiculous. No, I don’t need two hours to drink my coffee; Rather, I drink two coffees + an unquantifiable amount of tea over the course of any given day. It’s nice to keep my beverages consistently warm over the course of my day at work. The plug-in saucer is a bit campy. Couldn’t they at least figure out a wireless charging situation between the mug and saucer? The copper prods are a bit ghastly-looking. Not to mention the charging “saucer” is not liquid-proof and needs to stay completely dry.... so much for catching spills.
Despite all my complaints, I’ve still used this 20+ times in the last five days, so the concept is clearly solid and the product is functional! I just wish it fit more seamlessly into my routine.

Like the review before me, I find it burdensome that I have to keep the cup in the saucer in order not to loose battery within an hour. I work and walk around the house so having to find a place to plug has been inconvenient, so it defeated having to walk to the microwave to warm my coffee. The taste of my coffee changes to a ceramic taste after 30 min or so. Most days when I try to connect the Blue tooth for my mug with the app, I get the message mug cannot connect try again. So I do 3 or so times out of 5, I have to delete app and uploaded again to reboot my account. After so many tries, I am frustrated and upset. This mug was supposed to keep my coffee warm with my control of temperature via my app and blue tooth. We’ll, it fails it purpose, it’s more inconvenient that microwaving my coffee as I go along. It’s a good as a gadget, but for the price of $100, it’s way overpriced. By the way, you can get the mug at Starbucks for $75 which was a bummer for me after paying more through their website. Save your money, find another product that works as it claims. Customer service gets an F.

Perked up my mornings!


Amazing! I love it!!!
This was a Christmas gift I’d never have bought myself because I usually shun everything unnecessarily electronic since electronic hardware all seem to break too easily and smart internet enabled devices that require pairing have crappy software that wastes too much time keeping it working for you (just returned 8 smart plugs because they wouldn’t work in concert- after wasting three hours on hold and talking with various customer service people who could only read over and over from the same instruction manual because they had no idea how the devices worked and so i clue how to solve the problem except to keep asking if i was sure I’d updated the firmware)
Anyway- this thing works! It’s easy to set up and it works.
I sure hope it lasts a few years at least.
