Bests & Worsts Reviews from Amazon

I literally don't even understand how this is listed as 4k, 240hz and has even one positive review. It's visibly blurry around text, menus, much less video. It's laggy like I've never seen. Literally tryingt o watch ANYTHING (streaming or not) is horrible lag. I didn't even know that could happen. It's absolutely NOT 240hz, especially at 4K. When I went to plug in the HDMI I discovered every port is labelled 4k 60hz. I thought maybe there was a menu item somewhere to switch it to at least 120hz - nope. The lighting is extremely uneven. The AndroidOS forces you to sign into Netflix even when trying to cast from your phone - which is so stupid - totally defeats the purpose of casting. Just an all around horrible product. I don't understand!
