LARQ Bottle PureVis 500 ml - Self-Cleaning and Insulated Stainless Steel Water Bottle with UV Water Purifier and Award-Winning Design | Reusable & Travel Friendly| 2-Years Warranty, Obsidian Black

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.

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+++

This is an honest review, I’ve loved LARQ for a long time, and enjoyed using this bottle, but with minimal use and it just being in my backpack for London commutes and in the office, all the paint is scratching off and the rubber from the ‘UV’ lid is falling apart. Do yourself a favour and just buy a regular bottle, not even a UV one, I genuinely feel that this is not worth the big investment. The cost is not worth it, this is coming from someone who has 2 of these and I’m going to return both for a full refund. It’s so bad and not worth the money. £10 for the quality control it should be!

Very happy with this product

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 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.

This is a well made water bottle and it keeps the water cold with a few ice cubes for along time. The fact it kills unseen bacteria in water with its uv light is an added bonus.

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.
