The device is very useful and deserve at least 4 stars however, I received it and I was surprised that the battery was totally drained and the unit was not powering on! I noticed that it is start working for few seconds when I bend the power cable, then I used another 12v power supply and the unit started working and charging. the box was not sealed so Why you have not checked the unit before you ship to customer! for me the unit looks a returned unit as it was having some dust on the edges. this unit made to be used by installer, so maybe they think we will fix it for them!! now I am using another power supply which is for another system!

You need to use a touch pen or an eraser on a pencil for the touch screen. If you do not the screen will select features you don’t want. It is easy to use. But it takes a little time to get used to how it operates.

The device was purchased for use with FCC testing HDMI product. But the device failed FCC radiated emission testing when present as a benchmark.

I'm a broadcast engineer and I know the manufacturer overseas which builds this product. This product is very cheap and the manufacturer that builds it is a complete joke, literally all there products are garbage when we test to validate the product.
