I don’t have to think about reheating my drink, which is very convenient during busy work hours. The capacity is just right and the copper finish looks clean and modern on my desk. The mug feels solid and well made and the warmer heats evenly and reliably. Overall it does exactly what it’s supposed to do and makes everyday coffee more enjoyable. Read more

I travel constantly for work, so having my drinks stay hot is non-negotiable. I’ve tried so many heated mugs before, but the VSITOO S3 Plus has honestly been the BEST experience I’ve had — especially as someone who lives on coffee during flights, airports, and long overnights. The temperature control is amazing. It keeps my coffee at the exact heat I want (I personally love it on HOT), and it stays consistent the whole time. No more sipping lukewarm coffee halfway through boarding or during a long gate hold. It seriously makes such a difference when you’re always on the go. The battery + warmer combo is perfect. The mug alone keeps my drink warm for hours, but when I set it on the charging base, it becomes a full heater. I love that it’s auto-sensing — I don’t have to press anything, it just knows when the mug is on the base and adjusts the heat. The design is beautiful and durable. I’ve taken it in my tote bag, my work bag, my suitcase… and it still looks brand new. The matte black is super elegant, and it feels very high-quality in your hand. The stainless steel interior also means no weird smells and super easy cleaning. Perfect for flight attendants, travelers, or anyone with a busy schedule. I use it at home, in hotel rooms, at the airport, and during layovers. I even take it to the aircraft when I’m doing my preflight so my drink stays hot. If you’re a coffee or tea lover, you’ll love this. Overall: This mug has replaced all my other heated mugs. It’s reliable, strong, keeps the perfect temperature, and looks classy. If you’re someone who’s always running, flying, traveling, or just wants a hot drink without reheating 10 times — THIS is it. Worth every dollar. Read more

This mug is a game changer for drinking my coffee and tea. The mug itself can keep my coffee hot for 2-4 hours. It also comes with the included charging coaster which can keep it at the perfect temp for as long as I need. It’s great to take to work as well and I know my drink will stay hot even after a long commute. The AI sensing is also amazing allowing for hands-free heating and control. It’s strong and made of durable materials built to last. Definitely recommending to my friends and family. Read more

I know this is half the price of the Ember mug, but ultimately you get what you pay for. There are several issues with this product. Number one, the app user experience is extremely poor. It constantly disconnects from your mug, which means you have to re-pair the mug with your app every single time. There’s no user manual in the app, so I don’t even know how to pair it sometimes; it’s hit or miss. I think you just press the button for two seconds or something, but the Bluetooth connection is very inconsistent. Number two, the battery lasts less than two hours at 145°F - more like 1.5 hours, so you’re only getting about 30 more minutes compared to the Ember mug. Additionally, the app doesn’t allow you to preset the temperature; every time you close the app, it defaults back to the manufacturer’s preset. The charger plate is quite big compared to the Ember mug too - kind of bulky. I will be returning this mug. I am very disappointed. Yes, it is half the price of the Ember mug, but I would gladly pay more for a more premium feel, a better app, and a more consistent user experience. I did reach out to their customer support multiple times - they've asked for my device and order info., then disappeared - and did not provide any assistance with the issues. The frustration with this mug and the app is not worth saving $50 over the Ember mug. Read more
