I bought this as a Valentines gift for my wife and she loves it. The setup was quick and simple. This is perfect for when she is in the office all day, has a long commute or is at our daughter’s soccer games in the cold. You can set the temperature and it will keep your coffee at that temp for hours.

If you like your coffee really hot this won’t help you. If you like to maintain a comfortable drinking temperature and your a slow drinker you need this.

Gift for my wife, she absolutely loves it, however, the battery leaves a little to be desired. She has to take the charger with her to work.

Omg Love, love, love! I got this as a gift and I am so pleased with it. I received the travel charger as well for those long trips. Buy it, you won't be disappointed!! I already had the small mug for at home and it holds a charge for the same amount of time.

Very good travel tumbler even if you have to be very careful not to let it warp a bit on the top where you close the lid. Most likely it is because of the difference in temperatures that the material starts to warp but not to the point where liquid starts spilling out.

This was a Christmas gift for my son in law and he loves it. I also got the car charger for him as he does plow snow and this will keep his drink warm when he is very cold. No more cold coffee while sitting at his desk either!! The best of both worlds!!

Great concept. However, without the phone app it’s hard to adjust temp., the battery life is less than 3 hours, you can only fit about 11.5 oz even though it says 12, and they make you purchase the automobile charger separately for an additional $50. Definitely not worth the grand total of $250 after tax when there are a few other options that are significantly less expensive.
On top of all that, BestBuy stated that this item is a non returnable item. Save your money and look into other products that offer the same for 1/4 of the price.

Great concept and mug. I love that I can carry it around. However, the battery life is terrible. The point of a travel mug is that you can travel with it but the battery is only good for a couple hours, maybe. So if you are a coffee sipper or one that drinks multiple cups a day you may want to invest in additional chargers so you have one at work and home, which is disheartening seeing how much the mug is to begin with.

My wife loves it; her coffee gets cold by the time she gets out of the house for work, and she has to throw it. It is a changing game with this mug. She made her coffee this morning before church & she loves it.

We're actually returning this. It dosen't charge when there's coffee in it and my husband is on the go at work so he's constantly leaving it behind coming back to cold coffee. It's supposed to last 3 hours but that must be for the coldest setting because his dies within 90 minutes.

Bought this as a gift for a coffee drinker. Keeps the drink warm at the temp you want. Rechargeable. Displays battery life left, message you can set up and temperature. Charge good for about 3 hours. Pricey but unique.

Always gets my coffee to the perfect temp fast and reliably. Only issue is the fingerprints on my black model, maybe the red would've been a better choice but happy regardless

I bought this as a Father’s Day gift for my husband. I loves it and uses it almost every day. I wish the battery lasted a little longer, but that’s just me being picky. My father has one and loves his also.

The main value proposition of the product is that it will keep beverages warm. However, a fully charged battery runs out in less than 2 hours when not on the charger, thereby defeating the whole purpose. Even if you have the mug on the charger, the battery gradually drains.

My mom loves this thing... got it for her for Christmas and she goes everywhere with it. Sometimes when she’s in a hurry she’ll just pour water into it and heat it up on the way to work. Her only problem it the battery life but that’s it
