UV Self-Cleaning Water Bottle, 18oz Insulated Stainless Steel Tumbler with UV-C Purifier, Rechargeable Self-Sterilizing Cap, Kills 99.9% Bacteria, Keeps Drinks Hot 12HR/Cold 24HR

Excellent, use it all the time. I feel I'm drinking clean, sanitized water.

This sterilizing water bottle is great. It has a large capacity, wide opening, and keeps cold liquids cold very well. The sterilization process is easy and the notification is nice. The outside is nonslip. I would buy this product again.

I bought this in October and within the first month, it started to not hold a charge for longer than a couple of days. Recently, I noticed the cap inside, where the light is, is cracked. I don't know when it happened or how, but I called the company. They told me they were going to send me a return auth, but I never received it. I called Amazon and they said they would contact the company as well, but I haven't heard diddly from either. I'm very disappointed with them.

Very good

Will use it on road trips as you never know what water will be like, place to place.

I brought this up water bottle back in Oct. 2024. June 2025 it just stopped charging and the light of the top just blinks off and.on when I tried to charge it multiple times. It was good and reliable in the beginning. I'm very disappointed because I took very good care of and had a.lot of pride.in it until it stopped working and am now at a loss. I wish that I knew how to get a replacement cap/top. I'm having issues loading my pictures from my tablet, but this is my honest story and truth.

Keeps drinks cold lie it's supposed to. Easy to use. The charge lasts a long time.

Firsthealth UV water bottle. I’ve never used it to drink from but as equipment to clean filtered water. My home’s pipes are extremely old. I use it to fill up water bottles & ice cube trays
