PureVis Smart Self-Cleaning UV Insulated Stainless Steel Water Bottle | 24h cold or 12h hot, leak-proof, no sweat, BPA free. Reusable metal water bottle for travel, gym, running. 740 ml, O. Black

I have been using the bottle regularly for over three weeks now and there is definitely no need to clean it - the cleaning system works perfectly and seems to be safe, fast and silent. Did not notice that water has a different taste and was really pleasantly surprised for how long the bottle keeps the warmth if you pour in something heated. Also, dropped it on the floor already a few times and still everything works properly so it is clearly highly durable. Love the color and the design - overall quite satisfied with the bottle and the experience.

Bought this for my 11 year old daughter to take to school as her previous bottle was developing mould around the mouthpiece. What a great bottle!! Arrived following day before 1.00pm, in fact before 9.00am!! Beautiful packaging!! Easy to use!! Great quality!! And.. above all.. my daughter loves it!! In fact she drinks from it all the time and is more hydrated than ever!! It may be a bit pricey but worth it in my mind!! Also bought the carry sleeve from Larq's own website which fits like a glove around the bottle!! Highly recommended!! A+++

The LARQ Bottle has exceeded my expectations in both design and functionality. What makes it stand out is the built-in UV-C LED technology that helps keep the bottle (and your water) clean by neutralizing bacteria and odors. It’s a clever feature that gives real peace of mind, especially when traveling or refilling from less reliable sources. The self-cleaning mode is easy to activate and means the bottle stays fresh without constant scrubbing. Charging is simple with a USB cable, and the battery lasts surprisingly long on a single charge.

I wish I could give no stars. Second Larq bottle I have bought that failed after first charge. Bought first from curry’s and when the battery ran low I charged the lid. Then every time I tried to activate the cycle a red light happened. Curry’s accepted a return and refund no problem. I thought I would try again as I loved the bottle while it worked. Bought from Amazon this time on the Larq store and assumed the fault would have been rare and amazon are good with returns. But this time exactly the same thing happened again. After the first charge it had a red light. I followed instructions to reset it and got white lights and red lights but no blue. Came on Amazon to send it back and the return window is just a month. The battery lasts more than a month so no way of knowing if faulty before then and I’m sure Larq know that. I have done further research and it’s a common fault. So I paid a lot of money for a water bottle that lasted me less than 2 months. I’m very annoyed about this. Please Amazon extend the return window to 3 months to give time for the battery to run out and the fault to appear.

Here are my comments as a professional microbiologist. We bought this bottle primarily because we're off to Mexico where drinking water quality is highly unreliable. Even bottled water can be seriously contaminated with microbes in this country. It's not supposed to exceed 500 culturable E. coli-like cells ('coliforms') per 100 ml of water but one study found 23,000 coliforms per 100 ml. The bottle is nicely designed - sufficiently streamlined so as not to get snagged on stuff in backpacks and probably robust enough to survive a few knocks as it's mostly made of steel. When all is said and done, however, it's just a sturdy vacuum flask with a UV lamp built into the stopper. It's claimed that the UV light 'neutralizes up to 99% of bacteria'. This sounds impressive but if you were unlucky enough to start with bottled water that had 23,000 coliforms in 100 ml (see above) then you'd still ingest more than a couple of hundred after the bottle had done its UV zapping. Bear in mind that microbes such as E. coli can double in number in around 20 minutes under optimal conditions so UV irradiation reduces - but doesn't eliminate - microbe contamination. The other concern is the power of the UV lamp in the bottle, which LARQ doesn't state. Disease-causing microbes such as Cryptosporidium and Giardia are covered in layers that protect them from low power UV lamps. This means that they might not be inactivated by the water purification system used in this bottle. In short, this bottle is better than nothing but LARQ's rather hyped claims need to be treated with a hefty pinch of salt.

I am very satisfied with this purchase - both the order process and the delivery went smoothly, and the bottle is really good. I tested it by leaving the water in for a day and turned the self-cleaning on the next morning. It didn't have any weird smell (which usually happens in my other reusable bottles). The isolation works well, holds my water cold the whole day. The price is higher but it is worth it for the quality and style that you get.

Great value for money. Holds enough water with no spillage. Much better than bottled water

Great water bottle, sterilises water on the go.

This cup is awesome It really does work

Mine broke down within a month it never charged or worked again and the lid is stuck i can never open it and it’s past the return time

Excelente botella Super contenta con La compra!!!

Die larq Flasche ist mit Abstand eine sehr teure Flasche, wenn man einfach nach einer Trinkflasche sucht ist man hier falsch. Wenn man aber nach einer hochwertigen und qualitativ hochen Flasche sucht ist man hier gold richtig. Die Flasche ist sehr gut verarbeitet und man fühlt das es sich hierbei um ein Marken Produkt handelt. Die beworbene kalt/warm Haltung ist sogar etwas zu gut da heißer Tee sogar bei offenen Deckel teilweise 1.5-2.5 Stunden braucht um auf trink Temperatur abzukühlen. Man kann heißen Tee einfüllen und die Flasche für 6h in die gefrier truhe legen und der Tee wird immernoch angenehm warm sein. Die selbst saüberung funktioniert sehr gut und die Flasche fühlt sich merkbar sauber an in Vergleich zu anderen Flaschen. Das schmeckt man auch raus. Der Akku hält mehrere Wochen ohne Probleme. Wer eine gute Flasche für allwetter oder lange auflüge sucht hat hier die perfekte Wahl gefunden.

I really love this water bottle. Yes, the price point is on the higher side, but for someone who drinks a lot of water all day and doesn’t really want to have to wash their water bottle regularly, this is perfect. The battery lasts for several weeks. I washed it once when I first got it and haven’t washed it since. It’s been a couple months now, and the water looks, tastes, and smells just as clean as it did on day one. Since this bottle uses UV light, it’s only killing bacteria for you; it’s not doing anything to eliminate minerals and/or heavy metals. So as long as you fill it with filtered water, it stays fresh …… pretty much indefinitely, it seems. Super happy with this purchase.
