Netflix works standard and high quality only on Mecool K6, at least for the moment. But I doubt that it will ever be certified for Netflix. For séries it's good enough for me. Not much of a ntflixer myself.
If it is important for you, with a similar hisilicon chip and android plus openatv or enigma2, recommend checking out the Dinobot u5 mini 4K if you want an android satbox certified for Netflix. The Dinobot is twice the price than the Mecool K6 though. Other than dual boot and Netflix full support the two boxes run equally silky smooth.
The remote is indeed basic. I complement it with an air mouse. Curiosity, the same airmouse does not work on the Dinobot that has its own BT airmouse integrated with the remote.
The Mecool K6 box is all about the hisilicon chip for audio and image support. And I am very happy with it.
