LARQ Bottle PureVis 740 ml - Self-Cleaning and Insulated Stainless Steel Water Bottle with UV Water Purifier and Award-Winning Design | Reusable & Travel Friendly| 2-Years Warranty, Granite White

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.

Took it on holiday last week. Filled it up with water from public fountains and tap water from bars and cafes . It kept the water cold and there was no after taste once the water is treated.

I bought this bottle in June 2020. I liked the design and the self cleaning mechanism. However, after a year the paint on the inside of the cap is starting to peel off. It seemed this was due to the water on the inside which makes the paint swell up. Little bits of paint were then getting into the water inside the bottle which is a real health concern. If you look at the photo big chunks then came off. This looks to be a design fault, i.e. why is there blue paint on the inside of the cap.? I only had the bottle for a year but am disappointed that this happened and means I can't use it anymore. I contacted LARQ but after much back and forth and initially promising they would sent me a new cap they said I bought the bottle from an "unauthorised retailer", i.e. I bought the bottle of Amazon marketplace and not directly from them. They did not admit that this was a serious health risk or design flaw and in the end only offered me a 35% discount on a new purchase. A new cap would have been £40 after applying the discount. Very disappointing. Given I paid £100 for this bottle I must say this was not worth the money.

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.

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.

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+++

Great product and although a bit pricey the results are worth it. The water tastes fresh and clean. When I compared the taste of water straight from the tap the difference was really notable. It keeps the water cool all day too. Brilliant!

The media could not be loaded. I’ve had this bottle less than a week and have used it for cold water only (this insulated version can take hot water, but I haven’t tried that yet).I just tried to open the bottle, but it was really hard to unscrew. When I managed to open it, I took a drink and tried to replace the lid, but I couldn’t.On further inspection, the grey rubber/silicon seal had unseated and turned itself inside out.It took quite a lot of persuasion to get it back in place.Not good, from a bottle costing £118!!!I am thinking of returning the product but I’ve discarded the box now so it’s probably going to cause hassle.
