Perfect Robust Love the bag to carry ,Works 24 hour and slightly more actually keepsdrinks hot, we tested it out,so I bought another for,a dear friend of oursNo leaks, easy to open.No scratches or marks still despite having a bump .Price well worth the money. Do Buy you won't be disappointed, I've searched many a flask this is the best

Stays hot for 8 hours and cold for whole day.

My daughter loves it, especially the cup with its handle and the easy pour spout. It keeps hot drinks hot for a long period of time with the cover, but without it, by lunchtime it's manageable hot.

Unlike many others, this flask actually keeps hot drinks hot without the outside of the flask burning your hands. The cup/lid is also far sturdier than I imagined and is really good. The thermal carry jacket is an extra bonus which makes this flask brilliant on a walk. I love the purple/pink colour too.

Works well good size quality.

This flask is fantastic it does exactly what it says and does keep you’re coffee hot all day and night. It’s pretty, and strong. The carry bag is really useful and makes carrying it so easy. Great purchase I thoroughly recommend it.

Nice looking flask, but a bit of a pain to clean, and found it's a bit messy once you've had a brew and put it back on the top.

Doesn't retain heat as much as previous thermos flasks I have used. Also very difficult to get clean. Leaks at times as the seal isn't very good.
