Photo just for comparison sake
There's a lot of spots and shit because previous drawing tresspassed the paper and also that blue line is because marker straight up fell from my hand. Clumsy.

I'd probably say it's on par at best, depending on the controller's condition. Once the controller is updated via firmware, it connects specifically via Bluetooth LE, so it might not work with older hardware that doesn't support LE mode. It's worth it if you can find a good discount

I never used Stadia as a service, but a few months ago I bought a controller used on eBay for around $10 plus shipping. Putting aside the fact that it was a pain to disassemble and clean, it's actually a really solid controller once it's had the Bluetooth patch installed.
