I do not have a complete opinion, it did not work for me, maybe it is the fault of the Samsung A70 phone. When I tried it with the Huawei P20 after some time, it worked with several interruptions though.

I successfully and comfortably connected tablets and laptops to screens, TVs, and projectors. The resolution I tested was 1080p, and I don't have an opinion on higher resolutions (the sources - tablet, mobile - had higher resolution, but the receiving devices - TV, monitor, projector - were set to 1080p. In this case, it worked perfectly). The feeling of build quality is good.

4 stars because, although it seems that the converter is black, I ended up receiving it in white color.

Initially in the photo it is black, what they sent me is white.
Regarding its functionality now, I use it on an hp laptop with a USB type C port to connect it to a Dell monitor (I need 2 monitors but the laptop only has one HDMI). The screen flickers sometimes as if the connection with the laptop is lost. It's not to the point where you can't work, but it's still annoying. I would recommend going for a more expensive/branded purchase. I bought it mostly as a test to see if the setup I wanted would work.

Quite good construction for its price, I have it for about 1 month. It can be used on Mac as well as on Samsung Note 10+.
