The touchpad and even the buttons are way too sensitive. Always accidentally touching the trackpad and buttons or over or under shooting selections. You think you are tapping to go right and it thinks you are tapping right and then down etc. Even the physical design itself was poorly thought out as in a darkly lit room, where many people like watching TV, it is hard to distinguish up or down when going to pick it up (which again causes accidentally doing something with the touchpad). They improved it slightly with the 4k remote at least by putting a raised white circle around the menu button, but doesn't help those who already bought the previous version.
My parents (67+) absolutely hated it, eventually gave up and switched them to a Roku with physical buttons they could easily feel and see without always accidentally hitting something.
