Product Recommendation by Jen: (Jen is not part of our review team, but we welcome submissions!)

Jen did an initial test of this mug and found that it is indeed very resistant to being knocked over when placed on a hard, flat surface. However, she had a more difficult time releasing it, because the cup needs to be picked straight up -- not at an angle (i.e., towards you). Also, the flip top to open the mug might be a great design for some individuals but was difficult for Jen. This could be a great cup for some individuals with decreased fine motor control or coordination, but it was not the best fit for Jen. 

That said, the Mighty Mug product video offers a good demonstration of how this product works and might help you determine if it's a good product for you. They offer a 100% happiness guarantee, and it comes in many colors and varieties (including a tumbler with a straw!).
