Ember 16oz Temperature Control Smart Tumbler Mug Slate Black: Stainless Steel, Hand Wash, Hot Beverages

Thankfully, I didn’t spend my own money on this—received it as a gift. Unfortunately, that’s the only upside. This tumbler is more of a tech gimmick than a practical product. It lacks proper insulation, so once the internal battery dies, your drink loses heat rapidly. On top of that, the lid with the sliding mechanism broke after about a year of light use. For the price, it’s just not worth it. You’re much better off investing in a well-insulated mug or tumbler from a more reliable brand.

Mug is great but sliding lid is crap, broke pretty quickly after purchasing and replacement lids are always out of stock.

Got th8s as a christmas gift and love it. Wish they would make a car charger that plugs into usb as my new truck doesn't have a cigarette lighter plug.

Part of the lid broke almost a month ago and Ember customer service is completely radio silent. Apparently this is a major problem that many people are having. Do not buy any of their products until they have a customer service team again. It’s borderline a scam at this point.

This is the best mug ever . Keep my coffee warm all day . I'm very happy with the product . 3 hour is enough. It's good for working from home and drinking coffeee from home or spending half day at work . I love this tumblr. Upgraded from the mug .

Bought this "Special Edition" Topo AS SOON AS it came out and the lid leaks ALREADY. The mug is FANTASTIC, but what good is it IF THE SEAL HAS TO BE REPLACED CONSTANTLY!!! 4 months???? It needs to be better and it would be PERFECT. LOVE the topographic map AND the 16 oz size!

This is an ill-conceived product. As an avid smart home enthusiast (Home Assistant), there is one major rule to smart devices. Take away the smart and it must function perfectly fine as a dumb solution. The tumbler has no vacuum or any insulation to it and so not only is it not energy efficient which would make the battery last much, much longer but it also is useless the moment the battery is out. The charging is slow, there is no good way to charge while on the road. It's just not good enough, especially for the high price.

I've had this product for 3 months. It slowly started losing its charge and would die almost immediately after I fully charged it. Not worth the money, you might as well get a coffee mug warmer and save yourself a large chunk of money.

I got this for Christmas this year and it is honestly the GREATEST gift I have ever gotten. I have had the insulated mugs (stainless steel and plastic). I have had the hot plate style coffee cups that supposedly keep your drink hot. I have had every kind of mug you can imagine and this is the first one that ACTUALLY KEEPS THE COFFEE PERFECTLY TEMPERATURE! Since Christmas, I have used this mug every day 3-4+ times a day and it's absolute perfection. When I go out to run errands (in the arctic midwest cold) it maintains it's temperature beautifully for several hours. When I'm home, it comes around the house with me as I do chores... or more accurately, sits wherever I forgot it until I come back to it and it's still perfect for drinking. If I get a latte from a shop, it's almost never hot enough, so I've started bringing Ember (who I named Brewella DeBean) and it heats and holds the drink exactly where I want it to be. This mug is perfection. It's actually saving me money on coffee because now I'm not dumping out the ice cold cups I forgot about to make more or wasting store bought drinks that got too cold, too fast. I'm obsessed. It's amazing. This is the absolute perfect "busy mom" mug ... we've all done the, I guess I'll just microwave this cup I forgot about thing... and then forgotten about it in the microwave - Ember solves all that. This mug is excellent.

Really poor insulation. As soon as the battery dies my coffee quickly turned ice cold. For a travel mug I expected it to retain heat for a bit after the battery dies. I’m very disappointed, I loved my mug for home but the travel mug does not measure up.

I absolutely love my tumbler!!! I got this for Christmas and it’s such an amazing gift! I have used it every single day since Christmas for my coffee and tea. My spouse got me the 10oz mug a couple years back and while I love it I always wanted more capacity and the ability to take it with me in the car. The tumbler is perfection for this. I can take my coffee on the go and it will stay hot the entire ride! I am hoping ember will create a car charger for this size as well since the travel cup catcher doesn't work for the tumbler. That is my only ask! Fingers crossed!!

This item is heavy and awkward. It holds the 16 oz that I needed, but it is tall and has no handle. Disappointed! The curved bottom is the same as the mug but with the height it makes wobble and easy to tip over. I have the ember mug 2, that I love but it is too small. Why don't they just make a 16 oz mug with a handle? Make it just a little wider and a little taller to make up the 2 oz and dont forget the handle! I'm so frustrated that I spent that much money for something I dislike using.

Does not last! I bought the traveling ember as a gift and after 2 years it no longer works. The cup says it’s charged and when you put the coffee it says it’s not charged. Save your money and just buy a double insulated stainless steal travel mug.

I work in a medical office where I constantly need to go in and out of the rooms. I hated, hated, hated with a passion coming back to my desk to a cold tea. I was previously using the 14 oz ember mug but I wanted a larger one with a lid to prevent dust from falling into my mug. I also wanted a mug that could hold the battery for long car trips This one is AMAZING! I wash it every night, let it air dry, and fill it with warm coffee before heading out. The battery charges fast and lasts me the 1-hour trip to work. I always finish the tea before the battery, I haven't had any issues with it. I wish the company would create a car travel charger for this mug as sometimes I completely forget to charge it at home and my car rides are long.

This thing shouldn't leak if it's meant to be a travel tumbler. It has all the trappings of something that's leak proof- silicone gasket on the lid, a sliding bit to close the opening- but alas, the coffee stains in my purse say otherwise. This thing travels with me, upright, solidly closed and sealed, in a purse where it is largely stationary as I sit on a train. Then I walk less than half a mile and somehow in that time coffee escapes through the closed lid and drips into my purse and onto my computer and keys. If I was going to be carrying this thing in my hand instead of sticking it in my purse (closed, upright and stationary!), I may as well have just gotten the mug with a handle instead of this awkward slightly-too-big-for-my-woman-hands-to-comfortably-carry-for-very-long size tumbler. That said, the lid does at least prevent total spillage while traveling and when my kid knocks it over. It does keep my coffee at the right temperature and the app is fine, so the major draw of this product holds up. Just seal future iterations of this thing up a little better, please.

Exageradamente satisfecha,, lo maximo,,,ahora disfruto de mis te de canela y café a cualquier hora calientito

Got for my husband and it is great! Waiting for Ember to make it in purple for my daughter - hint hint

Great product. Excellent features. I received as a birthday gift & i love it! I never have to drink cold coffee again.

I have had Ember for multiple years now. Started with the 1st gen to go cup now on a 14oz regular cup. Would love to see a 16 or 20 oz regular cup to enjoy a nice cup of Joe at the desk or a weekend morning.

I rec'd mine as a gift on Mother's Day and used it EVERY DAY since then. Love it
