Hello, straight away, I'm with this Panasonic product more than satisfied. Two years ago I bought a Sony Blue Ray player and was very satisfied. Now I have recently purchased a Panasonic 3D plasma TV and it lies not have to wait long until I "needed" also a 3D Blue Ray Player. The Rezesionen some Amazon customers have me some very unsettled. From because of the player's loud. The only thing we saw on running / fan noise is at the start. In the film itself we could hear nothing negative with the best intentions. The sound and picture quality is unimaginably good. The Sony was already great, but this 310er Pansaonic is breathtaking at least for me as a normal citizen. When upscaling of good DVD a significant increase to 2 year old Sony can be seen. Access to Wi-Fi works fast and flawlessly. BD-Live is virtually on its own. Buyer of the player not forget a good SD card to buy. As I said I am very satisfied. Also because of the fact that I only have a remote control for everything. Have fun, R.
