I have been using Hollyland HDMI wireless transmission systems for a while (300, 400s) and they were performing great, so this time I was not concerned with the range at all.
I decided to upgrade to Mars 4K so I get the best resolution from a cinema camera to a consumer-grade tv and into an iPad at the same time and it is working perfectly. I use it for HDMI from smaller cameras and SDI from Ursa and it is great. Mars 4K also establishes a connector faster than the earlier version (important for some cameras when you enter the menu as they start sending in different output resolutions). It works perfectly so there is not much more to say
