Baffect 1 Litre Thermal Coffee Carafe Jugs, Vacuum Insulated Coffee Pot with Press Button Top, 24 Hour Heat Retention Vacuum Jug for Coffee Tea (Black)

It actually keep it hot, not warm!

This is rubbish. It doesn't seal properly & therefore does not retain the heat. DO NOT BUYThis is a rubbish product that does not do what it claims

So as far as plastic flasks go, this one has visual appealBUTWhile it will keep the morning coffee not-cold for a wee while (if you repeatedly tighten the seal using the screw at base otherwise forget it) it makes THE most annoying sound as it constantly leaks steam from the top. Like you can hear it from the next room despite being slightly deaf annoying. If you have any suggestions for a flask that looks good AND works, please let me know. This one ain't it unfortunately. Hope this review saves you a few quid and another bit of plastic from landfill.

We use one for coffee, & the other for keeping wine cold when outdoor in the summer. It keeps liquid hot and cold (respectively) for hours. Works really well. Need to be careful when cleaning as the inner glass compartment comes right out. This is great for cleaning, but it's a delicate process. Product recommended though!

First use no issues. Then the second unstated leaking from the bottom. Opened and the glass cylinder had a creak in it. Only had rinsed from the first use, so can only assume it cracked with the heat from the boiled water.

Don't keep liquid warm for long

When pouring hat water into the flask the inside thermal exploded shooting boiling water all over me and scalding my hands and face

I bought it twice, really it's good and keeps the water got for long time
