"500ml seems to be the perfect size. The insulation is top notch. Water stays fridge cold for hours, coffee same. Fits perfectly into car cup holders too as advertised. I was sceptical about the ‘flip and sip’ lid because I usually can’t stand them but this one feels very secure and doesn’t feel like drinking out of a child’s beaker! Would 100% recommend. Have bought a 350ml too specifically for keeping milk chilled on overnight camping trips!" - Pete R.

    Wide mouth makes such a difference - like drinking out a cup

    With the warm weather and lots of outdoor activities, my wife was searching for a sturdy but effective metal flask. In the fortnight since it's arrived the bottle has become a firm favourite. The slim 500 ml size is perfect for throwing in a shoulder bag or a backpack side pocket and the handle on the lid feels really sturdy. The textured powder coated exterior is very neat as well. While we hoped for the orange colour, we've fast become fans of the verdant green colourway.
    We've only tested it with cold water and it seems to work just as advertised with cold water keeping its temperature many hours later.
    Probably the best feature to it is the wide mouth, that not only makes drinking out it easier, but crucially makes it more accessible to clean the insides (something I've been less consistent with when it comes to my Chilly's type metal bottle).
    Overall very happy with the purchase. It's priced very competitively (it replaced a cheaper but nearly similarly priced bottle from a high street store) and the fact the brand is endorsed by the website BuyMeOnce is reassuring to the long lasting values of this small family owned business.
    For reference, we initially considered a rival product from Black+Blum but having tried it at a Finisterre store (they had a co-branded version) we were left disappointed by the quality of the finish on it. Plus it's more bulbous shape while more aesthetically pleasing, wasn't that convenient especially when coupled with a very narrow screw top opening.

    Excellent made bottle that keeps my coffee/tea hot for hours. I love the fact that the lid is all stainless steel as well. Highly recommend for going plastic free.
