Genki Manta game controller lets you customize everything on its own screen

Genki's Manta controller, now on Kickstarter, has a small built-in screen that handles all settings — no separate phone or computer app needed. You can adjust how the thumbsticks feel, save preset profiles, and more, directly on the device. Early backers pay $189; retail is $279. It connects via Bluetooth, a wireless USB plug, or a cable. The battery is replaceable.
