glad i bought it

This flask arrives in a box with instructions. It is made of a smooth brushed metal and plastic and looks nice quality. The outer lid unscrews smoothly and can also be used as a small cup.This flask will be very useful for carrying a hot drink on cold days. I tried it with very hot (not boiling) water and it was still hot 8 hours later!If you forget to close the inner lid button, it is cleverly designed so that when you put on the outer lid it closes it automatically. Mine does not leak (but I notice instructions say they cannot guarantee no leakage, so it is probably a good idea to keep it upright!)The carry case is a good fit with a zip which zips smoothly. The strap is adjustable but it does not extend enough to go over my shoulder, I would have preferred it with a longer strap.The flask is good size to carry drinks for up to two people. It works well and is easy to use.It needs to be washed by hand (instructions say not to put in dishwasher.)I really like it, just wish the strap was longer - so rate at 4*.

This is a small flask, ideal for one.It keeps my coffee warm for several hours and I’ve not had any leaking.The carry case helps with the insulation and makes it easy to carry.It’s easy to clean and fill.
