High Heat Retention
The product is really good for the price. I put in boiling water as at 10am on a Sunday and by 10am on Monday, I dispensed some water from it and it was still very hot with steam coming out, I left it till 10am on Tuesday and the water was still very much hot to the touch. For the result of 48hours hotness retention, I recommend it. Plus it is stainless steel which means you’re not as much at risk as flasks with glass.
