February 17, 2021: this is a day 1 review. So far all As. This is an attractive bottle though I obtained it because of the self-cleaning function. I read lots of reviews in this product rates well on several platforms. Once open it is important to remove the small protective cellophane from the top of the cap and from the inner rim of the battle cap. These pieces of plastic ware so well placed that they can be easy to miss. However if you miss them they will likely interfere with the charging function or eventually end up floating around in your beverage.Given the need to be hydrated and a preference for fresh clean water the UV feature comes in handy. I likely won’t used to sterilize other surfaces but reviews and research suggest that using the In this way is effective for small items.Though the packaging says that the Is designed specifically for this bottle it does fit on other bottles as well.I highly recommend me a cover such as a neoprene to help protect the bottle and to provide a handle to avoid drops. I do know that the crazy cab company sells handles but I prefer a cover that protects my hand from the coldness of the liquid in the bottle.The only concern that I have can be seen in the fifth image that I added. After opening the lid of the box which is really held together by small magnets I noticed two small round items on my counter. These turned out to be the magnets which had become dislodged. Given this it seems that a warning should be included with this packaging. The small magnets are known to be a choking hazard for young children and can cause significant gastrointestinal problems if swallowed.I will update this review if my initial assessment changes.

5.0 out of 5 stars Perfect to purify clear water with UV Light
Reviewed in the United States on September 15, 2021
I used to own a Larq water purifying bottle. It worked great but it didn't last as long as I would have liked. I hope this lasts at least two years. If it does, it will last longer than my Larq did. I also like that I can use it to disinfect surfaces. The Larq did not offer that option for safety reasons. UV is not good for your eyes. Do not shine this directly into your eyes. It can damage your cornea and lens.

I like that this fits on a standard size insulated metal bottle. I have one myself, so I can use it to almost double the amount of purified water when I go on travel, if I bring my other bottle along. I did verify that my cap puts out UV light by seeing the slight blue/purple light that I could see. I didn't look directly at it, only looked at the reflected light. I will modify my review if I have a problem and get a little sick from water the next time I travel. I will also plan to take this when I backpack. Great way to purify water from clear water sources.
