Review on Thermos Stainless Travel Tumbler Electric by Inocencio Anas

This mug has so many great features, but Thermos lost the ball at the 10 yard line. It weighs 16 ounces, fits a Keurig coffee maker (barely), has a tea bag hook (!), has a small bottom for cup holders, has an equatorial notch for gripping, is stainless steel for easy cleaning, has an ingenious open/close -Drinking mechanism and keeps warm for a long time. Excellent stuff. So why four stars? The screw cap is made of ultra-smooth steel and gently tapers inwards towards the top. This makes the top difficult to unscrew (clean?) even with slightly slippery fingers, as well as difficult to grab and remove from a deep pocket such as a backpack or crutch holster (my situation). If it wasn't tapered or made from a slightly more textured or sticky material, this mug would be The One.
