VSITOO 15oz Smart Self Cleaning Water Bottle，Insulated Water Bottle with Stainless Steel, BPA-Free, AI Self-Clean, 30-Day Battery, Magnetic Charging for Travel, Gym or Office, White

Really good
I’ve been using the new bottle for a few days now, and it has completely transformed my relationship with hydration. This isn’t just a water bottle; it’s a smart, portable hydration system.First and foremost, the 1,000ml capacity is an absolute dream. I used to constantly refill my old bottle throughout the day, but now this one large capacity sees me through my entire workday, from morning coffee to afternoon water. I easily hit my hydration goals without a second thought. The size is perfect for my desk, my car cupholder, and it even fits in the side pocket of my backpack.The smart features, controlled via the app, are where the S1 MAX truly shines. Being able to set a precise temperature for my morning coffee (a perfect 145°F) and keep it there for hours is magical. For meetings, I set a reminder to drink water, and the LED strip on the cup glows gently—a subtle nudge I’ve come to appreciate. Locking the lid through the app prevents any accidental spills or button presses in my bag. The battery life is impressive, easily lasting 2-3 days on a single charge even with regular use.Despite its large capacity, it remains surprisingly portable. The sleek Phantom Black design looks professional and doesn’t sweat, so I never worry about condensation on my papers or electronics. The build quality is exceptional; it feels durable and premium in hand. The carry handle is sturdy and makes it easy to take it on the go.In short, the S1 MAX is worth every penny. It’s brilliantly designed, incredibly smart, and holds more than enough for the busiest of days. If you’re looking for a way to drink more and worry less, this is the bottle for you. Highly recommended

It at least keeps water cold
The battery on the lid lasts for an hour at best. Do not buy.

Smart Water Bottle – Is Self-Cleaning Worth It?
I used to try a hydrogen-based water bottle but unfortunately, got broke a few days ago. I was searching for something new, and purchased this water bottle. It has special features, but the effective Self-Cleaning Smart Water Bottle has a compelling upgrade to traditional hydration methods. Build quality is very, very good. It has double-wall vacuum insulation which make this bottle a bit heavy however, this excels at maintaining optimal temperatures, keeping water hot or cold for extended periods. I have checked the temp and it was very consistent.The bottle’s standout feature is its self-cleaning capability. This new advanced technology effectively eliminates bacteria and odors (as per the advertisement) and addressing a common concern among reusable water bottle users.However, the “smart” features do come with trade-offs. The higher price point may be a deterrent for some, and the reliance on a rechargeable battery introduces a new maintenance aspect. Potential buyers should also consider the bottle’s long-term durability and the availability of replacement parts. Ultimately, for individuals who prioritize cleanliness, superior temperature control, and are willing to invest in cutting-edge features, this water bottle proves to be a strong contender in the market.

Won’t connect to the app
The reason why I picked this bottle is because of the app feature. Well, no matter what I try, the app would NOT connect to the bottle.The bottle itself is alright, it’s basically a thermos, nothing special.The UV light that disinfects the bottle turns on every time you screw and unscrew the top.It’s nothing special and not worth the cost imho. Giving it two stars as im assuming the disinfect function works (even though you can’t prove it), but it does not keep the water cool/warm any longer than your regular water bottle for a friction of the cost and the app to set up reminders does not work (it has 1 star review on Apple Store for a reason).
