Wait for the beta version

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.

Product is great, app... doesn’t work so well

I love my ember mug! It keeps my coffee nice and warm in the morning and just kind of nicely fades into the background. It’s almost a set-it-and-forget-it kind of thing. My biggest complaint is the app. The app has a few issues. First, I’m not sure if this is an app or hardware issue exactly, but the mug doesn’t seem to remember temperature settings between uses. I have to manually open the phone app and set the temperature (which, if it’s on “heater off” mode, you can’t tap a preset. You have to manually slide it over to the temp you want). It would be great if it would default to my last used temperature when I fill the mug. Second, the Apple Watch app doesn’t work unless my phone is unlocked when I open it. This kinda defeats the utility of the watch app entirely since I end up needing to have my phone out anyway. Lastly, I often don’t receive notifications when my mug has reached my set temperature, despite having notifications enabled for the app. If these issues could be fixed, the mug would be perfect! Ember, please fix your app!

Really great product

I read a lot of reviews, both negative and positive, before purchasing the ceramic mug. As usual, the ignorance of so many causes a really great product to be rated far lower than it should. The cup holds 10 ounces, yet so many complain that the hour plus heat time isn’t enough.... to drink 10 ounces. The notion that you need more than an hour to drink a cup of coffee is absurd. The saucer works well, as long as the mug is on the charger it doesn’t lose battery, so if you’re like me and drink 4 plus cups a day this solves any heating issues. I can easily enjoy my first two cups of coffee within the hour and don’t need the saucer, after that I just sit it on the charger instead of the counter, pretty simple concept. As far as the app, I’ve had no issues and receive notifications when my temp is reached every time. I have no complaints at all, and absolutely recommend this mug. I can’t speak for the travel mug as I don’t own it but the ceramic mug is fantastic. For those that see a product like this, do no research, then post one star reviews because they expected 4 hour heat times, they should be ignored. This mug functions just as it is described.
