Has anyone heard of Huff Paranormal on Youtube?

I want to discuss this topic with others on here if they have ever watched Steve Huff's channel called Huff Paranormal. This guy built a device that he can speak to the dead on the other side. He built & perfected this device called the "Ghost Box". Has anyone heard of that before? if so, do you guys believe in it? I honestly think it's real and that I just wanted to know other peoples opinion based on the device.
