TalUltra Bottle - UV Self-Cleaning Double-Wall Insulated Water Bottle - 18oz - Black

It is easy to operate and the water bottle seems very well made and is attractive. Liquid stays hot or cold as advertised. Water taste good, but I have no way of telling if it is functioning as is promised.

Best choice ever! Brings certainty to every time drinking water. Confidently drinking very pure every single day. Easy to use!!

It may clean water but the taste of metallic is what I could not stand. I could not get over the taste of the water.

I bought bottle to take on an upcoming vacation. I tested it to make sure it worked as soon as I got it and the water taste great. It is easy to charge and only takes a couple of minutes to purify the water. It doesn’t leak and I got it in black, it doesn’t show any fingerprints or dirt.

Wish it held more water but it's a decent amount, would buy again.

This UV self cleaning water bottle is made from good quality materials. The light is located in the cap and can be activated by just pushing down on it. Pushing it down once gives you a shorter cleaning while pushing it down twice gives you a longer cleaning. This is rechargeable and can be done just about anywhere. But the inside of the water bottle does not hold a lot of liquid. It takes a long time to charge. The lid has to be taken off to get a drink and honestly, I don’t know that the light is doing much of anything. I haven’t noticed a difference in taste or smell.

I like having this as a backup in the car because I know that it is bacteria free when I need it weeks later

With things that have UV cleaning, it's hard to really know if everything is working the way it should or if it's just hype, but thought I'd try this nonetheless. The bottle itself is good quality, has a slightly textured exterior for additional grip, and the lid screws on tight. The UV light is in the lid and dots light up to tell you it is running. Charge is fast and seems to hold.In theory, I'd never need to clean the inside of the bottle or the lid - ever. From what I can tell, this is mostly true as long as it's just water in there. If I put in something else, I do rinse it out well first, then run the cycle. No mold or anything wild growing in there so far. I do like that.The lid with the tech inside makes it a bit heavier than the average bottle but worth it for the extra value. Overall, I do really like it. If nothing else, the bottle itself is great quality.
