Milton Elfin 300 Thermosteel 24 Hours Hot & Cold Water Flask, 300ml, Silver | Leak-Proof | Easy to Carry | Office & Travel Flask

Bought these for work to supplement a faulty hot water heater. We would use a few of these and fill with hot water at the beginning of the day. The seal wonderfully and the water stays steaming hot through the entire work day, and fit well in just about any cup holder. Durable as well

It's a perfect size for taking in the car and it keeps beverages cold.

One of the best ..! Leak proof thermos’s on the market ..lite weight and it holds its temp..!

Searching online to find this product was rewarded with an excellent find. I’m not up for Everest etc though it would likely be valuable there. I need to carry water for medication. No chance of leaking. Just the right size.

Does keep contents at temperature well. Cap traps water when washed. I've let it sit over the weekend to dry, and when I use it again water still drips out of the cap that must be wiped up. Annoying. My lunchbox has ice packs and water condenses on the outside of the container. This didn't happen on my powdercoated container

Ideal for a work day accompanied by a hot tea or coffee, I loved it

This item was what I thought to be perfect for me. I don’t like using chemical coffee creamer and this was the perfect size to bring back and forth to work. The amount was enough for 3 days of morning coffee and worked well. Unfortunately, I have to wash my backpack because it leaked all over the inside. Then I thought I didn’t tighten it enough….still leaked. Returned for a refund, and sorry to do so, however when I buy something I expect it to function as designed.

Why, after decades of mounting evidence about the effects of food and beverages contacting plastic containers, are manufacturers of longterm-use containers still incorporating plastic? Had our family seen the interior-lid of this thermos, we wouldn't have wasted our time to buy it. We don't want our family exposed to the MANY (not just BPA) bioactive plastic derivatives that permeate liquids contacting plastic. Worse, the person I bought this for wants a small thermos she can take tea on errands in. Hot liquids and plastic should never mix... How hard would it be to just replace the interior plastic with another sheet of stainless steel? Way to ruin an otherwise great-appearing product. Plus two stars for size--small enough for a beverage while you're running errands. Minus three stars for plastic lid.
