Review on Innens Wireless HDMI Transmitter and Receiver Kits - Advanced Wireless Presentation Dongle Adapter for Laptop, PC, Smartphone - 4K @30Hz Streaming Video/Audio to HDTV/Projector by Aaron Parish

Works well. don't lie much. Somehow I have to constantly plug the transmitter into the USB wall charger to work, although the manual says to only plug it in when the computer battery is low. Crashes (becomes a green screen) from time to time. Don't know why it breaks but if used for business presentations and crushed during presentations. It would be kind of awkward. I only use it for home entertainment so it's not critical. So it always depends on the intended use. €200 is not cheap. I am 80% satisfied with this product.
