HYDRATEHydrated 500ml Leakproof Stainless Steel Bottle - Double Insulated to Keep Drinks Hot for 12 Hours, Cold for 24 - Sweat-Proof, Leakproof Screw Cap - Ideal for All-Day Hydration, Dark Blue

As advertised doesn't leak, the handle is a bit small and not to comfortable to hold. Keeps drink cool

Keeps hot drinks hot for 12 hrs and same for cold drinks.

Placed it in my back pack which I carry around all day and tend to sling about and it didn't leak.However It doesn't keep my black coffee hot for more than two hours after which it was warmish, but by 3-4 hours was slightly above room temperature . To be fare most of the metal "thermos type" flasks don't keep hot drinks... hot for very long. I'm not so sure the claim to keep hot for 12 hours stands up in practice."Thermos type" Containers with a glass vacumn inner tend to be more effective.

Great at keeping your drink hot or cold for hours

Got and cold drinks flasks I put hot boiled water and coffee in the morning from 6.30 lasts upto 1ish not cold but Luke warm cold stays colder for hours I brought my husband one and my self covers hospital ops where less mobile even holidays gyms well worth the money

Good value, easy to wash, easy to carry

Not a thing, the large top provides easy access for filling, and the additional small screw spout provides safe process for pouring.

I like my water cold, very cold and this bottle keeps my water cool not cold. The bottle itself is very well made and sturdy with a nice texture and popping paint job. I think the screw on top is what lets it down, the plastic is solid bit does not have the temperature retaining properties of a metal flask. Furthermore the crew on drinking cap is very time consuming to use. Overall it is a ok water bottle and not a very good flask.
