Razer, which makes gaming PCs and peripherals, has introduced Razer Kishi for Android, a game controller-type device for Android, for iPhone. When not in use, it looks like a compact gamepad, but when in use, open it to the left and right and plug in the Lightning terminal to hold the iPhone and merge it. You can expect the advantage that the button response is ultra-low delay because it is directly plugged in, not wireless.
The button layout is very similar to that of the Nintendo Switch. However, there is no headphone jack. Enjoy it via Bluetooth connection. The iPhone Laser Kish is also the first laser product available at the Apple Store. It also supports more than 100 games in Apple Arcade. The price is $99.95. IPhone SE is supported, but iPhone 6 or higher can be used. Related information can be found here .
