Purchased this product after a lot of research, all the best useable features without the over expensive price tag, glad I did. Panasonic's attention to detail for a 4K player was spot on. My wife and I watch a lot of old series on DVD that are not produced in Blu Ray or 4K and boy does this machine upscale to a better than normal DVD quality just beautifully, and the sound quality is fantastic, guess part of that is due to the TV we purchased also. All our set top boxes and players are Panasonic and this like the others doesn't disappoint. Plug it in and off you go. Thanks for stocking it JB HiFi and thanks for producing it Panasonic
