ProworksStainless Steel Water Bottle, BPA Free Vacuum Insulated Metal Water Bottle for 12 Hours Hot & 24 Hours Cold Drinks, Sports Flask Great for Work, Gym, Travel - (Panda, 500ml)

I bought the 500ml size over a year ago and use it every day. Despite being dropped many times, it still looks as good as new. Back then, that size cost me £21.94. This larger size (1 litre) recently cost me £11.95 and what a bargain it is. Firstly, it is stunningly beautiful. I bought it in the metallic red and the website photos do not do it justice.More importantly, it really does what it says. It keeps my cold water cold for at least 24 hours, even if I leave it in my conservatory in full sun (can get to 50 degrees C. in there). The outside of the bottle can be burning hot to the touch, but the water inside is wonderfully cool. It's pretty incredible.The other extremely good thing is the taste of the water, even the next day the taste is as sweet and pure as it went in. Previously, I had used Futurepace stainless steel bottles, but after a few hours the water tasted dreadful, however carefully I washed it out each day. I've had to throw them away.I can't say how long it keeps liquids hot as i only use it for cold water, but I'm sure other reviewers will comment on this.I have one of these in the 500ml size wherever I go as it's so light and judging by how I chuck it about, very robust.Finally, don't worry about leaks. It does not leak.Highly recommended.

I have used this on a recent family picnic and it did keep my water chilled all day. The screw top keeps the content secure and stops any water spilling out or anything getting in. It’s great if you’re sat in the warm all day as this helps you cool down as it just doesn't warm up. Fantastic quality and design at a much cheaper price than I’ve seen in the shops.

I ordered a 750ml white one of these flasks as an Amazon Warehouse deal, which is almost half the price of some of the other colours so that alone is great! I see that there are almost no reviews for the white bottle, and presumably many people think white may be impractical as it could start to look grubby quickly. However, these bottles are so well made, with high quality materials, that that wouldn't be the case if they're kept normally clean! I have a 1 litre flask like this one by a different brand and like it but it's so big that it's not practical for me to carry around on a regular basis so I wanted to get one that's a bit smaller and slimmer and this one totally fits the bill. It's great - sleek, stylish, sturdy, easy to use and even came with a long handled bottle sponge cleaner (but these can also easily be washed by filling with hot soapy water, swilling that around vigorously inside, cleaning the neck and outside well, and rinsing, then letting dry by standing it upside down to dry the inside). Some people have commented that theirs don't keep hot drinks hot for as long as the product details claim - to do that the flask needs to be warmed up a bit first by filling it with hot water for a few minutes, then filled with the hot drink. For cold drinks put the flask in the fridge for awhile before filling with a cold drink. Simple! I love my flask and intend to get a 500ml one too. 😃

What a stylish, great looking flask. Shiny outer finish - I got a black one - looks really cool. It really does what they claim. I have used it for hot drinks and they remained virtually at boiling temperature for 8-10 hours when I took it to work. I have also tried it with cold, fruit flavoured water and that stayed chilled for the duration of my working day, about 10 hours ! This is probably the best flask I have ever used. I am most pleased with it and would recommend it.

I absolutely love it! Got it for a bargain price for 1L and i brought it to keep my babys water for formula at a hot temperature and it works amazingly. It kept it hot for longer than 12 hours. I am happy I came across this seller, I will definitely order another flask from this company!

I bough a 500ml and a 75-ml bottle and the lid doesn't stay on on he 500ml bottle. There is no thread to close the bottles, with the lid merely push-on on.I partly filled both bottles and if tilted, (not even close to being inverted) they leaked considerably, with the water inside then pulling the lids off. I am not able to return it (disability) and so am furious about this. I wish I had bought another brand. Don't waste your money. I would be happy for the seller to contact me to offer to collect it and return my money. I would them purchase robust metal bottles. My aim was to avoid plastic bottles- which don't tend to leak, so it looks as though there is no reliable alternative to plastic bottles if this is the quality of the metal alternatives. Not happy.The blurb on the box states ""leak-proof performance" and "stopping water getting over your office desk or in your kit bag", which is exactly where this design seems to ensure the water reaches!

Straight out of the box, you can tell this is a substandard product. For a start, the casing comprises too many parts for good insulation. Before using it for the first time, I hand-washed it in warm soapy water and the pattern (it was the strawberry design started to flake off). That was it: I decided it was going back, but I needed to fill it and use it one time. When held upside down, there was a slow drip from the lid. If that's how bad it is when it's brand new, I wouldn't want to keep it longer. Pound-shop tat. Avoid.

I am so picky when it comes to shopping for myself. And this bottle had an amazing combination of functionality, design and quality. The surface is scratch-free, the bottle is a perfect size and leakproof, really does keep water cool even in very warm surroundings (haven't tested other way around yet).The camera does not do it justice. It also appears slightly thinner on my camera than it actually is.Thoroughly recommend!
