I bought the IView to play Karaoke from MP3-G files. It claims to play from USB, SD Cards etc, or CD. USB works but I tried an SD card in the slot and it wouldn't fit. Oops. Navigation among karaoke files is quite limited, only showing the first few characters of the file name. I had to rename files to remove the artist name from the front of the filenames so I could get a hint of what song I was selecting. Pressing stop takes you back to the first song in topmost directory. The remote has to be pointed directly at the machine to work. As noted by someone else, the mic is weak. I'm keeping it though because I don't want to spend more and I think I can make it work for me.

If the microphone were a little better, I would give it 5 stars. For the money, it's a good buy. Should do everything the home user would want.

Very cheap for player that come with 1 wire mic, has HDMI connection can read your USB flash drive, SD memory card even can read Hard Drive, I alsa used it for watching DVD movie
