Hey, you, what controller do you use for emulation?

Converted-to-Bluetooth Stadia controller.

It's actually a really nice controller. The ergonomics are great for my big meaty hands, it's got some weight to it and feels really solidly built. The heft means the vibration really has some kick to it. The battery life is really good too - it was specced for having Wi-Fi on all the time, so now it's running only a little Bluetooth LE radio, the battery is massive. Even when it runs down, the charge rate is quick - full in about half an hour, and then good to go for weeks. Again, probably because it was specced for Wi-Fi, the radio circuitry is way above average and the range is stupid - I can control a Steam Deck from two rooms away, through two solid brick walls, something none of my other controllers can do.

The sticks are accurate and don't drift, the buttons are pretty good, and the D-Pad is a bit stiff but perfectly serviceable. My one significant complaint is that the springback on the triggers is way too light, which makes it difficult to be subtle with the triggers, a little annoying for driving games.

Still, if you see one at a sensible price, they're a steal.
