PS3/PS4 to PS3/PS4 Super Converter (Yellow)

I recommend updating the firmware first. This adapter is great, love looks of it. Plus its very useful as once paired with a controller it remembers it. So if you plug and play; you plug to switch it works, change it to pc the same controller still works (as xinput). No lag issues tested with a WiiU pro controller(actually wakes up console) and dualshock 4(gyro works, so its like a pro controller, doesn't wake up console tough, and touchpad works as capture button).
I don't give it 5 stars only because there's no place to put the cap while in use, so maybe it will get lost.

it is a very good adapter.

as always with 8bitdo

Very functional when using in the PS3 and PC, connect the controller to the converter usb port, press the home button and that's it (if you want to use a PS wireless controller just wait some seconds after plugged in, disconnect it and turn it on again).

Turbo mode is OK, I hadn't checked the remap mode because I don't need it but there is a problem when you use this converter in the PS4, the controller and the converter just turn off by themselves after some minutes, doing a firmware update from the official brook webpage can solve this.

First off, I'd like to say it works. The red lights are a great indicator of whether or not the controller is plugged in, most of the buttons are mapped respectively. This is where I come to my problems with the adapter. We are down 3 buttons. 2 due to the GameCube controller's design and 1 from the adaptors design. Now losing the select and one of the z buttons isn't a complete loss, but you really appreciate the start button once it's been removed. On the switch, it's now registered as the Home button. I get what they were going for, but now I can't get past the opening cutscene to Blaster Master Zero. On paper, it makes sense to make the start button a home button. However, the start button is very much in a large number of games.
Now it does work with other games on switch fine if you don't need the 3 missing buttons. I think what it's best for is experimenting on other USB compatable devices. There's bound to be creative ways to us the adaptor, but on the switch it feels hindered and that's just because of one button.
If you want to use a GameCube controller on a USB compatable device this is so far the best priced item I've seen on the market.

What I would recommend to make it better? Well I find the Turbo Button unnecessary so if that can be removed in place of a home button that would make the placement all the more fitting. If there is a way to have an extra z and add a select button through the adapter I welcome it, but I'll take the home button idea if Brook will consider it.
