Stainless Steel Smart Tumbler
Product Details
Web ID: 4895939So-so for the price and promises
I had my Tumbler mug for 2-3 years. During that time, I found that the battery life was so-so, at best and charging was commonly frustrating. I always added hot liquids to the mug, so I never asked it to heat from room temperature (this alone will drain the battery), but even then, unless you're planning on drinking pretty soon after filling, the clock is ticking! Maybe that is also because I like my coffee hot -- the max temperature this thing will go to -- and the battery life times they quote are assuming you like your coffee somewhere between hot and room temp. The mug almost always had to be "jostled" or twisted (or whatever) in the charging disc to get it to begin charging, a routine that took several minutes every day. I had to replace the charging disc once during this time, as the contact points are prone to damage. Last week, the mug finally died for good. I'm on the fence as to whether I will replace it or see what else is out there. I notice that Ember has not redesigned or otherwise improved the Tumbler since it was introduced. Seems odd, as this should be the low-hanging fruit for them.

Doesn’t work all the time.
I bought this last year around Christmas and had not used it. I just started using about a month ago and the idea of it is great but sometimes it turns off by itself, sometimes I turn it on and pour coffee in it and it says it’s empty on the app. I cannot set a timer on it and to be able to work I have to keep it on the charger.

Bad product
Too bad in terms of battery life. From 85F to 135F it took 1 hr and took 80% of the battery.

Disappointing and Overpriced – Just a Tech Gimmick
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.

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

Not so practical
Short usage time when not on charger. Higher temperatures shorter usage time.
Good Coffee Mug
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.

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!
