WarmieWonders Smart Cup

Keeps drinks at the perfect temperature. Only way I’ll drink hot liquid

Bought one for my grandmother and she loves it! No more microwaved coffee.

OK ... So I waited several months before writing a review. Initial thoughts ... Ember does a Great job keeping your coffee hot! Certainly much better job than some of the inexpensive options (e.g. better than Brookstone per my personal experience). Definitely keeps me from having to reheat coffee in the microwave every 10min ... HOWEVER, the Ember does not solve for one of my key challenges. I tend to drink coffee with Cream & Sugar. And when you re-heat creamy coffee, it tends to burn a layer of milk that sits on the surface (it's terrible ... ruins a good cup of coffee when you drink that muck by accident). And sadly, because the Ember does such a good job keeping coffee hot ... this same phenomenon tends to happen. And more specifically, it tends to happen if you leave those last few sips sit too long (tends to super heat a bit as you get to the bottom of your mug). I'm thinking I could probably try to adjust the Temp setting as I get to the bottom ... but I rarely remember to do that. So all said, Great mug ... but not Perfect. And yes, for the record ... app still kinda stinks. Doesn't happen all the time, but mug often loses Bluetooth sync.

Ordered a used cup, said it was in very good condition. Upon arrival, I smelt a burnt order eminating from the package. In short, the cup did not function at all, it was burned up. But, I requested a replacement and it arrived a few days later. It was in excellant condition and works perfectly, so far. I am very pleased. However, they should check the functionality of their product before shipping it.

The app is completely uselessThe mug itself does work with an auto mode, it will keep itself warm when it has liquid.Good enough to keep coffee warm
