RGBlink Mini-pro V3 Video Mixer Switcher with 4 x 4K HDMI Inputs, Dual HDMI/USB3.0 Outputs, PTZ Controller with 2.1-Inch Touch Screen, Ideal for Live Streaming, Worship, Gamers, and Live Events

Does what says on the box … great value

Solid portable TV station, switcher, i use it for podcast and for karaoke party, you can switch between 4 inputs and up to 2 monitors as program, the multiview is a program output too.

Display reagiert sehr langsam, separate Aufnahmen der einzelnen Kameras nicht möglich. Bild und Bild Funktion schwierig einzustellen

This product is good , but they need more video training on how to use the switcher vs you looking it up to get similar products to practice on

Si cumple con lo que dicen más la imagen obtiene un pequeño grado de latencia con respecto al sonido si este va por separado, pero en general un switcher estupendo.

Simple... This device works, very limited. It's not an ISO recording device (it does not record multiple cameras individually). Would not update firmware or connect to the internet. Yes, a little learning curve and you really have use this device as a post production switcher in my usage case. If you buy it, not a bad product at all when using for extremely simple things as a podcast (small personal things). Just glad I had a backup plan. It's not bad, just does not hold up to the description. Make your own opinion. Two (2) Stars, for over promising with functions. Three and half (3 1/2) Stars, just overall of the product. RGBlink needs for me to be silence tester or publicly of their products.
