I have had a few media players in the past and all have had some bad points. But this one I have no complaints at all with. It plays a very wide range of formats from avi, mp4, mkv,iso,img, h264, divx etc the list goes on. Both video and audio are supported very well. So are some internet streaming services just too much to put in a review.
This unit does not have wifi but there is a USB Wifi dongle available also specifically for the A110 HD. Plays from PC's, Media Servers, or Straight from a UPnp NAS drive.
