Does NOT leak!

With this travel mug, when you have it in the cup holder of your work bag and the bag tips over, you do not have to worry about it leaking. Unlike other travel mugs, this one screws in tight and does not leak. That's why I have four in all different colors.

Thermos Brands for me!

I love Thermos brand., and this one is great. The pink color is really beautiful, and it is really easy to hold when just walking around or taking a drink. The lid keep the liquid inside and is really tight fitted, and the spout for drinking allows liquid to come out in a nice flow, not pouring out leading to spillage. It really keeps drinks cold for hours as well as keeping hot drinks fairly hot after a couple hours. All in all I highly recommend this product.

Very nice

I love this .. The only thing is It is a little hard to get the mouthpiece when you want it. I had to screw the lid on several times to get it right but it kept my coffee hot for at least 3 hrs
