Royalford Stainless Steel Vacuum Bottle 500 ml, RF9780

Waste of money, you get vacuum flask in cheaper rate but it will lose its property of keeping hot within a month, the entire flask becomes hot from outside when you pour hot water in it that means there is no vacuum left to retain hot and that too within a month of usage.Don't buy it

This is a good quality bottle. The only problem is that the top has a form of press down in unlocking button to let the water flow out, its a bit not easy to use. and also it holds in some water inside. It needs to be cleaned all the time. Otherwise it can get a bit slimy. You cannot fully fill the bottle because the top unlocking mechanism takes up a bit of space inside the bottle and is difficult to switch open by pressing down sometimes

Nice product

After 1 month of using it started to loose the thermal interior and it was extremely hot to touch, water would become cold quickly.

Hot water will become cold within 1-2 hours

This product has no ability to contain warm water. I was shocked to find the water chilling cold after an hour or 2.

I have bought this one but it doesn't even keep hot for more than 2 hours.

Single walled......won't keep the coffee hot very long.....useless.
