Because I write a lot of reviews on Amazon, I get emails with "New products that may interest you."
I got this one Mengshen Self Stirring Glass Mug which has no reviews to date.
I scrolled down and was surprised to see that there are a bunch of these "self-stirring" vessels. And it's only 350ml, isn't that about 12 ounces? That's not big enough for me. My coffee mug is 16 ounces.
Have none of these people heard of a spoon?
I have a self-stirring cooking appliance because I don't want foods to scorch. I guess it is too much effort to remove a lid and stir a beverage by hand. I can see this being a good thing for someone who is disabled but they don't seem to be aiming at that market.
