Self-Stirring Lens-Shaped Coffee Mug for $13 w/free S&H

I suppose this falls squarely into the Dads and Grads gift season, it’s not just a Lens-Shaped Coffee Mug, BUT a Self-Stirring One! No, it does not use gravitational waves harvested from the soul of the universe, but two AAA batteries to power the self-stirring which is activated with a button on the side of this 11oz lens-shaped coffee mug going for $13 with free shipping with a limit of five per customer at Stacksocial. There is a short video demonstrating the stirring over there. Delivery estimate is two weeks from today.

PS: I have only used the non-powered ones, so I don’t know how well the stirring works on this one.
