Ive owned mine 3 years. Watch a ton of movies. Worked perfectly about 9 months. Than started getting finicky wouldnt load brand new 4k discs. Say couldnt read or disc error. Thats gotten worse. It reads blu rays and dvds fine. But apparently the 4k laser has become worn. I even took apart and cleaned the lens. When it played 4k discs,great picture,and never froze. Movies that froze on my sony es1100 played thru on my pani. I may buy another,BUT INVEST IN A PROTECTION PLAN. Which is something I never do. Good luck happy watching
