No real problems so far. Got them in the wild and super easy to config and set up. I do have one weird one though: Moip system (obviously) using the split out of the transmitters to feed a local AVR (Pioneer SC65) that then goes to a JVC DALIHA 4k projector. All sources work fine EXCEPT a ROKU4 on the AVR. When fed directly to the AVR, the ROKU is fine, but when going out of the MOIP pass through, no joy (all cables good and under 1 meter). I'm guessing an unfortunate mix of HDMI chipset or voltage combo...
