I got this in January and am very pleased with it. Watching 4K movie versions such as the 4K Wizard Of Oz and 4K Jurassic park, for example, was worth the price in my opinion. Amazing color and detail.
I have a fairly new 55" Fire TV which may help—I don’t think the difference would have been so noticeable on my older smaller TV.
Ordinary Blu ray are also sharp and clear as are regular DVDs. I would definitely buy this 4K player again.
