This bluray works well. It has a very clean design and I like the simple touch interface on the from of the unit. My only major criticism is that you see the USB input onthe front of the unit in the store and assume that it is like most other bluray players in that you will be able to transfer a movie from your computer to a flash drive for the purposes of watchin in on your TV through the player.
However, this particular model only supports .mp3, .wma, .jpg formats. (mosic and still pictures). The unit is not programmed with the ability to read .avi, or .mov, or any other video format for that matter. Therefore, you will probably almost never use the USB port on the machine. It's a video player... that won't play videos (at least from the USB input, anyway).
For that reason I rated it average for performance. Otherwise, it is a nice bluray unit.
