I wanted a flask that would keep my coffee hot throughout my work day. This does just that. I wanted durability, without the fear of breakage, as I store it in my work bag in the car for lunch breaks.The sleek and simple design is very aesthetically pleasing, but it is the practicality of this flask that really stands out, for me. It keeps my coffee hot throughout my working day, even when it is kept in my car.The wide neck of the bottle is a very good design concept. I can easily fit a washing up brush in there to clean it thoroughly, plus I can fit in larger ice cubes for a cold drink in the summer months.I chose the stainless steel finish as it can get bumped around a bit at work, and I won't have to worry about paint chipping or scratches.I've had no leaks from it whatsoever.With the 3 different lids it comes with, and the choice of additional accessories, this makes this flask a great 'all-rounder' to suit your needs.Quality construction andI highly recommend this flask, as it does what I wanted it to do.
