I purchased this tv to replace one. I chose the Roku after having a positive experience with a Roku streaming stick. This replaces the Samsung I had for several years. I find the navigation screen to be very user friendly, the tv is very responsive, and I was pleasantly surprised by the sound quality. I would compare it to being in a movie theater. Roku will be my new go to product when it comes to buying a tv.
I have really never thought that I would invest in a 4K TV, thinking they were a little over the top. But now, I stand corrected and didn't realize what I was missing. The best part is the Bluetooth. I can use my headphones and not be disturbed or disturb others with what I'm watching.
