Review on Thermos Stainless Travel Tumbler Electric by Jennifer Martin

Great mugs. Silver in my photos is over 6 years old. I use it almost every day for coffee and water at work. It used to be dark blue. The paint came off pretty quickly (maybe a few months after using the dishwasher) so I peeled it down to stainless steel and used a mug. Color doesn't matter for performance. This mug will keep you warm or cold for a very long time and the lid will not leak when closed and properly filled. If I fill it with ice water and leave it overnight, the ice cream will be in the cup in 16 hours. It looks big but with double insulated walls it doesn't hold up as much as it seems. There are several later models of this cup. One with 360° transparent cover and the other with sliding opening. Both are inferior to this older model. I returned the vented cap model as it leaks through the closed lid and also doesn't insulate due to the cheap lid. I was happy to see this model on sale after so many years. This bright blue looks great, but I'm not sure how long the color will last this time. Just take a look.
