I have connected the Evolution kit to my UE75ES9090S. The installation went without any problems. Infected, current again turned to the unit and. The installer then ran smoothly. Updates I have activated and no problems with it. The entire smart functions run much better, the new design (a matter of taste) I find it very successful and greatly facilitates navigation. The best new feature, however, the included remote control, which touch function is finally to control now works correctly point exactly is. Two (small) drawbacks for me - I find the new remote control is a bit on the small side ... and unfortunately you have to sort the channels actually back that will not be accepted. Apparently however, Samsung has learned to do so because the (new) Evolutionkit settings can be saved as a backup so that they then remain at a recent change. Is that worth 200 euros? I think yes. Finally, one has indeed already invested a lot of money in a TV, but can be as truly customize the unit repeatedly to the latest conditions. Depending on your mood you do not have any evolutionary stage join yes.
