Push Button, Drink Hot Coffee. Repeat.
This coffee cup doesn't leak.
Yes, I have spilled coffee down my work clothes from leaky coffee cups.
I have also broken the lids of coffee cups in the dishwasher.
I have melted plastic travel coffee mugs and lids in the dishwasher.
And- I have been known to take two travel mugs in the car with me on the way to work. One cup is for the car ride. The second one is for work.
This is the best travel coffee mug I have ever owned.
First, this cup really doesn't leak. There is an airtight seal. In order to take a sip of coffee, press a button. Release the button, and the cup seals itself again. Brilliant.
Second, this cup keeps my coffee so hot that I have to be careful not to burn myself. In fact, instead of waiting for the coffee to cool, I usually add a bit of extra milk before I screw on the cap. (The insulation works so well, that the coffee doesn't cool quickly enough for me to enjoy it when I need it.)
Third, it holds 20 ounces of coffee. I shouldn't consider this one cup of coffee-but I do. This large cup gets me through the commute and the first hour of work.
Finally, the cup comes in many beautiful colors. I own a purple one, a black one, and a silver one. I use my cup for coffee in the morning, and switch to tea in the afternoon. I own three of these cups because I like to be sure one cup is always clean. My husband loves them too.
