Google bills Stadia as "one place for all the ways we play" — meaning on TV, desktop, and mobile. But considering Stadia's games aren't controllable by touch, playing on a phone can get awkward. Enter the Claw: a made-for-Google phone cradle custom fit to the Stadia controller. It's not great, but outside of Stadia's inherent drawbacks, it does facilitate phone play, and for $15, you might as well pick one up.
It's very difficult to review something like the Tablet Claw. For starters, my first instinct is to make the entire thing one big Inspector Gadget joke. Then there's the fact that I have no idea why anyone would need this. The Tablet Claw is a device that you slide your tablet into, and a little plastic piece that kind of looks like the tab you open soda cans with (called a "ringlet", apparently) folds out and gives you a way to grip your tablet.
Okay, hang on, though. I'm an open-minded person. Perhaps there is a use case for this.
