Frequently Asked Questions (FAQs)

1. How long do stainless steel flasks last?

Stainless steel water bottles can last an average of 10 to 12 years before they need to be replaced. This is because stainless steel water bottles are generally durable, non-corrosive, and stain-resistant. They can tolerate impact and will not immediately show some signs of wear and tear.

2. Are food flasks any good?

Of the food flasks we tested, we think the Thermos Stainless King food flask would be best for soups. Not only is it affordable but it also keeps the contents piping hot for hours. Plus, the tapered top of the flask means it's much easier to drink out of - but of course you can use the foldable spoon as well.
