my dad has one of these and takes it every were. Inspired by this i decided to get one and am very inpressed it is sturdy heavy duty overall a good product. Love the cup it is not as heavy duty as the rest of the thermos but is still wont break easily. My only real complaint is that it dose not hold a lot of liguid. 24 compared to 48 is a little diffrent but how much do you actually need. All in all great product i highly recomend it and glad i bought it.
