Hi NILESH...
Here are my quick inputs:
Service of PANASONIC sucks in BLR. They are understaffed and attend calls very late. My rating for that POOR.
Picture quality is good. Viewing experience is pleasant, nice color reproduction and less strain on eyes. 3D is also good. If u r watching downloaded media then you will see some jutter which is all because of how the media file decoded / encoded FPS etc. Internet / wifi performance is good. Youtube videos plays well. Have not explored all of its smart features yet. No issues with external HDD detection. I have connected 1TB drive. Few file format did not play on this...i recall had issue with couple of .avi files though they are listed as supported version. Never had time to worry for those files. If you get hold of true blue ray files...clarity is awesome.
