So far, the device could play everything I wanted, Blu-Rays (clear) all look good, with DVDs I imagine at least perceive the upscaling effect. The formats I've played only .avi and .mp4 from a DVD, both of which were played without difficulty.
A major reason for me for the purchase was the Amazon Instant Video app, in the long run it was annoying to constantly make the Playstation. The app was pre-installed and after entering the login data of the access was possible. The login data will be also noted in the player, so that you are not forced each time to enter their data again. The app itself runs very smoothly, sometimes I have a feeling that does not run the video at the start in the best quality. This is, however, at the latest after a few minutes (but could also be due to my own internet connection). The control of the app via the remote control works without much practicing and is kept very intuitive. The only drawback of the app is that episodes from different series will not be automatically played in succession, you must instead return to the menu and select the next episode.
When negative (criticism at a high level) the player I feel only the very small remote control, which also is also strange in his hand, and the lack of Wi-Fi connection. Both points can get over, however, and not detract from the quality of the device.
Overall, the players met my expectations.
