Vsitoo Smart self cleaning Insulated Water Bottle, 8.5oz Stainless Steel Vacuum Flask, AI Self-Clean, 30-Day Battery Life, BPA-Free, Magnetic Charging, Portable Travel Mug Gifts for Men Women, White

Great performance like the previous model, but looks more elegant.
PROS: Masculine appearance, great thermal performance maintaining cold fluids, accurate temperature gauge, long battery life, quickly recharges.CONS: The self cleaning switch no longer actuates by touch.Have the earlier model that works extremely well, but has the pink/blush exterior color. This model matches the performance of the earlier model, but the black color with the gold lid is a winning combination. Using the item with bottled water and ice, the water will remain cold at least 24 hours. Very pleased with that performance. During a month’s usage, the item has worked perfectly and even endured a few tipovers without any noticeable damage. Repeat buy rating of 100%

It might be small but it is perfect for lots of daily events
This is the perfect water bottle for carrying for take medicine or in lunch boxes or on trips to the park it is small enough to fit in a purse or a pocket so you can get water out of a water fountain anywhere and not worry about the safety of the water it is well insulated so if you get cold water it stays cold for hours it is very useful now instead of carrying a large bulky bottle to the park I just slide it in my pocket and use the water fountain knowing that the uv light wil sterilize the water without dulling the taste I personally have put this in my joggers bag and there is no leaks and taste still cold as when I first filled it even after a hour outside in the heat and opened and closed taken sips the the time

Promised features don’t match product
The appeal and purpose of this AI Water Bottle is hard to fathom, especially since features promised on the product page either don’t exist or are no longer free.According to the product page, you can use this bottle to keep track of your hydration–but neither the bottle nor the Android app keeps track of how much water you consume. The AI Self-Cleaning function does exist, but requires a paid subscription, which (at the time of review) is something that is not mentioned anywhere on the product page.Instead of a QR Code to download the app from Google Play, like nearly all smart products with a connected app, you need to manually do a search for Vsitoo to find and download their app. The app currently has a Play Store rating of 2.1 out of 5 with 114 reviews. The main complaint seems to be that the app became less useful with updates, and the message I got after adding my product, that the AI Self-Cleaning Feature now requires a paid subscription, is probably the kind of thing reviewers are referring to. The app also said (after a firmware update) that my bottle would no longer display the temperature of the contents and instead just use red to indicate that the contents were hot and blue to indicate cold–but as you can see my bottle still displays the temperature, although since it’s in Celsius and cannot be changed to Farenheit the number is useless to me anyway.This bottle uses UV Light to purify water, but that method can only kill viruses and bacteria. It can’t eliminate chemical contaminants, heavy metals, or sediment–and for most people in North America, viruses and bacteria are not the type of contamination likely to be found in their drinking water. If you drink water directly from a well, pond, or lake, then yes, that water could contain viruses and/or bacteria, but the Vsitoo Smart Water Bottle doesn’t seem like a product designed for people who live in rural areas or for outdoor camping.It’s possible that if you travel a lot or are a germophobe, having a water bottle with built-in UV Purification will provide some extra peace of mind, but for most people in North America, there isn’t going to be any practical benefit from the water purification technology built into this bottle.You also need to completely remove the lid any time you want to drink the contents, which makes it significantly less convenient to use than an insulated cup or a workout water bottle.Final Verdict: This Smart Insulated Water Bottle does not include any kind of function to help you keep track of your hydration–which, for me, was easily the most appealing feature listed on the product page. The AI Self-Cleaning Feature now requires a separate paid subscription, and the Vsitoo Android App has terrible reviews in the Play Store, which is relevant when you’re purchasing a Smart Product. This seems like a waste of money to me, but maybe I’m missing something.
