HC-Telecom's GOXLR is a great popular product, allowing you to split and control your audio on the go-live (perfect for streamers).
If you don't know much about audio equipment, then the GoXLR makes it super easy. The software itself can have quite a learning curve at first, and the body is unfortunately made of plastic instead of metal.
I'd recommend you have a big desk, and a good amount of space as compared to other interfaces, it's MASSIVE. I would personally consider the GoXLR to be a bit overpriced, today there are cheaper setups and alternatives.
Overall, I'd personally only recommend it to those who want something super easy-to-use, that don't mind paying the hefty price.
