VSITOO S3 Temperature Control Smart Mug 2 with Lid, Self Heating Coffee Mug 10 oz, Touch Tech&LED Display, Black, 1.5-hr Battery Life - App Controlled Heated Coffee Mug - Improved Design, Coffee Gifts

First, feature of adjusting temp from handle does not exist!!!! I did not feel that inner part is ceramic and more like plastic and health wise i do not think it is great!My coffee is 75 c usually so having max temp 65 c is not enough!Size is small for my requirement!I am considering it a regret!Used it a couple of times and back to the box!!

My wife is very particular about her coffee temperature. Me, not so much. I generally drink my coffee slowly over an hour or so and have gotten used to drinking it at whatever temp it happened to be when I sipped. But…..now that I am able to keep my coffee at the perfect temperature (for me) I am absolutely spoiled. I would generally not spend that kind of money on such a convenience but we purchased during Prime week and had points so were somewhat cushioned on the price. My wife and I both do really love the cups though.

This coffee mug does what it's intended to do. It can be operated by the VSITOO App or manually. The app has many functions such as changing from Celsius to Fahrenheit and temperature presets. The heating takes approximately 27 minutes from 25°C to 65°C. The app will also change colors to correspond to the temperature, ie: below 36°C is blue (cool), between 36°C-50°C is orange (warm), and from 51°C-65°C is red (hot).There is a multipurpose button which press and hold, will turn on/off the mug. When the mug is on, single press the button will toggle it's temperature from 25°C to 65°C, then goes to STOP, which means turning off the heating. When on hot, it's barely drinkable, you will have to slowly sip to be able to drink it.Right out of the box, it barely has enough batter to operate the mug, after it's fully charged it's smooth sailing. Once you turn it on, it will tell you the temperature of the liquid inside. I haven't yet tested how long the internal battery will keep the liquid at a preset temperature, but my purpose is to have constant warm drink while working. Having the ability to take it with me is a plus.

I first ordered one in March, 2023 and have enjoyed it so much that now that I’m back home in CANADA 🇨🇦 I’ve decided to get a second one so I’ll have one for my coffee and this one for my tea.I highly recommend the VSITOO S3 Pro Smart Mug. I’m a black coffee drinker and have to wait awhile for it to cool off. In a regular mug it gets cold and I have to mic it 2-4 times before I finish it. Now with the S3 Mug it stays warm for an hour or more if you put it back on the charger plate.I did have another make (EMBER) and was VERY disappointed in it. The battery kept getting weaker and when I contacted them they said sorry you’re 2 months passed the warranty. Then 2 months later the charger plate crapped out.

I have not stopped raving about this water bottle since I got it! It is the coolest little thing! It doesn't hold much liquid, 15 oz, but the bottle itself is awesome! It is pretty and pink, so I love the color, and it has a rubber bottom to keep it from falling over. The inside of the bottle is stainless steel and keeps your drinks cold or warm within its walls. The lid of the bottle is the special part Of this bottle. It acts almost like a thermometer with sensors on the inside to keep track of how cold or hot the inside of the bottle is. You just tap the screen on top of the lid and it will instantly tell you the temperature inside. It also has a neat feature where if you turn the bottle upside down and let the water run over the sensors on the inside it can tell you how pure your water is with the TDS rating. You can also set your bottle to remind you every once in a while to drink water! It is as if it knows when you open and close it so it knows how often you drink, and if you don't drink for a while, it will send a vibration reminder. The lid comes with a charger that magnetically sticks to the top. This is a unique charger, so if you lose it you will have to order another one exactly like it.This water bottle also comes with its own app! It is called VSITOO and connects to your bottle via Bluetooth. The app will tell you how much battery your bottle has left, the TDS of your water AKA how pure it is, will send you reminders if you have not had water in a while, and can adjust how long you want the bottle to stay turned on after you tap it. This is a cool feature. I absolutely love this bottle and think it is pretty spectacular!!*This product was given to me through the Amazon Vine program for my honest and unbiased opinion.

This cup is great just wish it was a bit bigger.
