Ember - Temperature Control Smart Mug² - 10 oz - Gold

First, almost certainly your question, like mine was before I got my Ember, is can a mug really be worth the cost? Don't they make warming coasters for around $20 that will do the same thing? After using my Ember for 3 weeks is, without hesitation, yes it is worth the cost, and no, a mug warmer is nowhere near a replacement for what Ember can do. I drink between 5 and 10 cups of tea a day, and I got used to the phenomenon that I could drink it when it was scalding hot or I could drink it lukewarm, but I had about a 60-second window of that perfect sip of tea. I'm very precise with my food and drink (for example, I time my tea steeping for exactly 1 minute and 20 seconds and exactly 6 mL of lemon juice per cup), so having a tea mug that can get my tea to exactly the perfect temperature for every single sip, no matter how long it takes me to drink my tea (137 F, in case you're interested)? That sounded too good to be true. And yet, it is that perfect. It took a little tweaking at the beginning using the Ember app (Ember actually encourages you to tweak it to perfection; they give suggested temperatures, but they want you to find your exact sweet spot), but then it is zero maintenance after that. Whenever I pour tea into the mug, it can sense that there is fluid in the cup, and it begins the processes of allowing the tea to cool down to the right temperature and then maintaining that temperature until the very last drop. And, I really mean it, the very last drop (as a small note, the last drop is slightly hotter than the rest of the drink because it's been sitting on the heating element longest, but frankly, that's a joy to get a small burst in temperature rather than having the last sip be tepid as I've been used to). I even get an alert on my phone and Apple Watch letting me know that the mug has reached the correct temperature so I can start drinking it at exactly the temperature I wanted. Also, the mug works, for a while, off of the coaster. I keep my coaster on my desk, but I can get about 2 cups of tea between charges (depending on how fast I drink it), so I can have that same temperature expectations when I'm away from my desk. I wish the battery was a bit more substantial (2 hours would have been somewhat ideal) or if there was perhaps a portable charging station that holds a longer charge. Or, I wish an additional coaster was a bit less costly so I could have them at multiple points in my house for more convenient charging. But, now we're just getting into wishlist territory, and none of those are a reasons to knock the product down in rating. There is one design flaw that I think is somewhat problematic, and based on some other reviews, I'm a bit concerned that it will end up shortening the life of the charging coaster. The mug itself is water resistant, which is helpful for a product whose sole purpose is to contain water (it is not water resistant enough to let it run through the dishwasher, but hand washing a mug that I use many times a day is not a problem). However, if water gets on the sides of the mug, it naturally goes down the side, down the curve of the bottom, and into the seam at the rubber ring at the bottom. This is fine, except the charging coaster is not supposed to get any moisture in it at all. I usually wipe the bottom of the mug with a paper towel, touch it to feel if there is any moisture, and still about 30% of the time, when I pick the mug up from the coaster, there is a ring of moisture on the coaster itself. Because using the coaster while drinking from the mug is how you can use it somewhat indefinitely, it's not an option to just leave the mug off the coaster. I have read reviews stating that the charging nodes on the coaster get corroded because of the moisture, and I can see how even the most careful user could run into this issue. Other things I don't love about it: the handle is a bit uncomfortable because it has somewhat sharp edges, and the lip of the mug takes some getting used to for the same reason. They kept the mug walls very thin (it is actually stainless steel coated with ceramic, presumably to both control the temperature through the entire mug more efficiently and to keep the weight of the mug down as it's somewhat heavy because of the electronics stored in the bottom), which is fine, except it lends to sharper edges. I got used to both of those things pretty quickly and haven't thought about it for the last couple of weeks. However, as far as design goes, it's a very attractive mug, and remarkably, the sides are always cool to the touch, even immediately after pouring boiling water into it, so it is clearly an exceptionally designed mug. I could go on and on about it, but the bottom line is that this is, no doubt, a luxury. It feels really hard to justify paying $100+ for a mug. And yet, it has completely transformed how I drink my tea, and every bit for the better. And, aside from a one important design flaw, rarely do I see such perfect implementation of technology. Well done, Ember.

I hate when my coffee goes lukewarm, so this was the perfect product to enjoy my morning coffee at exactly the right temperature. Super easy to use and clean. And looks great on my desk!

The cup does what it says and will keep your drink at the temp you want for a couple hours while off the charger. One call-out, if you don't get it put on the charger perfectly, it won't stay charged. Not a huge issue but, a watch-out. You will realize it the first time you go to grab it and it is dead but, has been sitting on the charger overnight. I would probably buy again and if the price comes down, I would definitely buy again.

This is my second Ember, which I bought to supplement the one I have. On the days I want two cups of coffee, sometimes I don't want to wait for one recharge before I start my second cup. On the charging pad, it will keep coffee warm all day, but off the pad, the limit is about 90 minutes. The thing I like best is that I get to set the temperature I want through the Ember app.

I never thought I needed this in my life, but the Ember cup changed my life forever. There is no better feeling than taking a sip of your cup of joe 2+ hours later (as long as cup is charging on plate) and realizing it’s still at that perfect temperature you set it at. Even my boyfriend feel in love with it, so I got him one so we don’t have to fight over the Ember cup. The copper mug is a really nice color and it doesn’t look like a tacky. Only downside is that these metallic colors don’t come in a bigger size.

I was given one of these a gift, and like it. My daughter expressed interest and since she has a birthday right after Xmas I thought I would get one for her. I'm not one to gulp down my coffee so I like that it keeps it warm for about 1 hour, without needing to be on the charging pad. Wish it were a little larger capacity. 10 oz seems skimpy. Battery life could be a bit longer. I wish it lasted 2 hours (I solve this by using the charging pad as a coaster) I've dropped this cup several times and it survives well. I think this should be about 1/2 the price

My Ember mug has quickly become the only mug I use. It has the feel of a conventional mug, but the technology inside keeps my morning coffee perfectly heated to the final sip. The app was easy to install and synchronized, but honestly, once I set the mug to my desired temperature, I haven’t used it. I would recommend this mug for anyone who looks forward to their coffee every morning like me.

I thought of this as rather frivolous - it was just a way to give myself something fun in the midst of the pandemic. However, it really does work and I use it almost every time I make coffee. I tend to get distracted and often end up throwing out coffee. With this, it's there, warm and waiting for me, when I get back to it. I do leave it on its charging coaster all the time if there is coffee in it. It has to have special handling - no dishwasher for it - and I wish it held a little more coffee. It only holds about 2 official coffee cups worth, not a big mug's worth
