Nice quality flask. Handy that the top acts as a handle. Seems to insulate for a reasonable length of time too. Not tried it with hot liquids only cold as our office doesn't provide chilled water. Keeps water cool for around 8 hours or so.

Great bottle amazing in keeping you drink cool in the hot summer but also warm/hot in the cold winter days.

useful, unbreakable and keeps drinks hot for as long as I need it too.

This bottle has made me feel like I have my first child. I love love love it. You forget how bad warm plasticy tasting water is very quickly after purchasing. It's encouraged me to drink more water, and the design is great.It is however worth mentioning that the wide mouthed 1l bottle does not have any additional drink cap options, so should you also want to use this for sports, I wouldn't get larger than the 750ml.I live in a hot country, and I fill my water at the water machine at work at 6pm, and if I still have some left in the morning the next day, it's barely warmer than it was when first poured. Crisp, cold, clean tasting water all day!(I also saw a comment below about someone who found the water sort of jumped out when they were trying to sip, and I do know what they mean, you just got to be patient and take your sips slow! Had I known that I wouldn't be able to get a sports cap, i may also have got the smaller size, you do have to stop what you are doing to drink!)

Fantastic purchase! I wanted a 1L thermos to drink hot water out of at work and to take 1L cold drink to the beach (mostly to make sure I was drinking 2L/day) It is just what I wanted! It’s a 1L but you can still drink from the top easily, or pour out if you wanted to drink from a container. The colour is really nice too! Came quickly with no fuss.

What can I say ? It keeps things cool for up to a day.

Perfect! Watertight seal, keeps liquid appropriately hot or cold and just the right size to fit in my bag.

I have four of the narrow neck thermal insulated stainless steel water bottles and think they are brilliant, so I risked one of these wider neck bottles as I thought it would be much easier to clean if used for hot soup or hot milky drinks. However, after putting in some boiling water whilst I heated the milk to a simmer, I then poured out the hot water and filled it with the hot milk and some drinking chocolate powder. Three hours later when I opened it to drink it, it was only lukewarm, so I will not be buying anymore of them, which is a shame, but my LifeVenture small thermal cup/bottle/flask does a much better job of keeping hot chocolate hot :/
