The one major thing that I disliked is that after multiple plays on a DVD, the unit muddies the disk (scratches?) and crates a gum-like substance on them. It does not play Blu-ray disks either. I have not yet tested the burn disk capabilities. the unit also does not have any device installer disk but luckily my Windows based laptop picked up the unit as a plug and play and I was able to use an HDMI cable (purchased separately) to have it broadcast to my TV. I have not tested this on a MacBook or other hardware other than a Lenovo windows-based laptop. Finally, I am still unsure about the added features nor the full extent of the battery life as I have not put through its paces and clocked the hours yet. Overall, it is a good addition for newer laptops that don't offer a built-in disk players.
