This Trudeau 20 Ounce Car Cup is Hot, or Cold or whatever you want it to be. It really keeps liquids hot or cold for a long time. I believe that the manufacturer claims it will keep liquids warm for 4.5 hours, and I have found this to be about correct.
This attractive cup fits in most standard cup holders. It seals tight and does not drip even if you lay it on it side. It has a larger capacity than many car cups and the amount it holds is just right for me.
Note: this particular cup is designed for right hand operation - If you want a left hand cup then try one of Treadeau's newer ambidextrous cups.
Its stainless steel construction makes it easy to clean, and it does not impart any taste to its contents.
This cup has a non-slip base and is relatively stable when used on a normal table of desk, but is probably more prone to tipping over than a standard cup. The metal part is heavy duty and will not dent, the plastic parts are strong and are not prone to breaking.
The cup is guaranteed not to leak and has a 5 year warranty.
